So I've got a service called a water leak, hoshizaki machine nice little panda. This is why nice ice stuff evaporator. So in this situation the first thing that we're going to do we're gon na turn it off and put it into a wash cycle. I just find the wash cycle the easiest to test it in SAP, because you're not playing with the compressors on and off so now we're going to test the bin thermostat.

You do so by pushing it into a pan of ice and Counting how long it takes to turn off loans of 22 seconds for the first, but I usually ignore the first. You need seconds to turn back on so now we're gon na test. It again in took forty seconds to turn off six seconds to turn around okay, so to defrost this I find the easiest way myself, just put it into the wash mode, with your cleaning doll straight up and down position. So it's putting water through the inlet tube.

Also and then just spray hot water in there, while it's still running the pump spray hot water in the drain, and just like that and you're gon na, like a pumpkin to work for you, this is from the top looking down. I want you guys to see what a freeze up so that's your evaporator down there see that's what it shouldn't look like with no ice on it, but see over here. It's backed all the way up. There's a couple things that cause Frieza.

The biggest issues are low water pressure coming into the machine inside been thermostats. What's the biggest things that cause freezers. Other things that I see too is, depending on the style of machine people, not putting the extension brackets on the band stacks yeah, but my two most common issues are low water pressures coming into the machine. Basically, when it's in a harvest mode, there's not another water.

Coming in gallons per minute, I shouldn't say water pressure who say it's not enough water flow, so you don't have to write gallons per minute. It doesn't because it uses defrost and water on these old machines to be possible to melt the ice off. So if there's not enough water coming in the defrost alone, sometimes won't get all the ice off. There's things we can do, we can extend harvest times and different stuff.

One thing I don't like, though, is that doesn't look like a big enough water line coming in here. I believe that we need, I believe, on a 1600 pound machine off the top of my head. I think we need a 1/2 inch water line. I eat coming into this machine, but I'll verify that with the mango right now that right there is like probably a quarter-inch connection like it throttles down at the end of that row is quarter-inch and it might be, creates ID on the inside of the tube.

But that's definitely too small. Interesting is that's a half-hitch water pipe connection coming in well. That could be wrong all overnight on the check. Yeah that definitely looks suspect right there, but so we're just running hot water through it, letting the water pump push it up into the spray rails and letting the water drip down over the ice.

Naturally, another tip is, if you can sometimes you can't, but if you can pull out you're you're cute guys and that way the ice. Does you drop down on the cute guys if you do pull the cube guide? You got to be careful, though, because not ice comes down with a vengeance ahead of us everything in here, so you got to kind of melt. It slow use your hand or hold it up. Just be cautious.

Okay, just understand that when you have freeze up suits out of this one, you're, probably gon na, have a plastic cube guide. This one is the most part, looks like it's defrosted inside now I got ta hit the outside. I'm just going to slowly do this now, I'm also being cautious, because there is electrical stuff over here and there's a solenoid up there, that's energized! So I put this cover on there, we're just doing it slowly, so we're not getting water but we're using the water pump to our advantage, so we're defrosted all the way I'm putting the cube guide back in. But before I do, I hold this side.

Cubed, I'm out and clean behind it as it was kind of difficult. You know you kind of want to do things efficiently. If you have the ability to to pull something out because you have all the water out or whatever go for it, I'm not doing a crazy cleaning on this machine, but I can pull it out and get this line. While I was waiting for this unit to drain so I drained the sump out, I'm gon na put the cube guide back in right now and then we'll turn it on and win and if you're working on these machines, this is your check valve or your pump Out spring, pull this off look inside so that sediment, that's your worst enemy that causes the pump out spring to get stuck open and the machine will run out of water early and do a premature harvest.

That's not a little bit the problem running into right now, but because I had it open a dream, I was checking it so always inspect your cube guide for any broken pieces or cracked pieces. Look at it really carefully, because sometimes it's hard to see them. Those cracked pieces will get lodged in the water pump and ruin the water pump worst case scenario, so you want to be cautious about that. So before I put the back together, this one looks good, but I just inspect it thoroughly.

It is very important that you get this cube guide back in there correctly. If you look up there on this edge right here, there's a ridge that can't be on this side, because the ice slides off into the vent see on this side sits on that lip. All the way down got ta make sure it's nice and secure, and it should not go anywhere. It holds itself in place if it's put in there correctly, I've gotten serviced Falls where we put the machines back together wrong, and this is slid down and Isis everywhere.

It's a mess, so got ta. Make sure you put these back together. The way you took them apart. I shouldn't say that you got ta, make sure you put it back together the right way.

It doesn't matter how you took it apart. You need to make sure that you put it back together right. I want to point something out one of the more common places that gets a neglected when people are cleaning. Is this tube right here stuff inside there and it's this valve and this up here? Okay, you always want to be cautious about checking those and make sure that, when you're doing a cleaning that you pull this tube off and inspect it so we're gon na rinse that out the machine itself looks really clean.

But I'm noticing that in the common places where people forget it's still dirty and we've yet before we started up we'll pull these spray rails and inspect pepper spray rails are actually pretty dirty to this dark discoloration in here and then down towards the end they're. Pretty bad some pieces of an old cube guide in there, so we're gon na get that all cleaned out. Look at that things are pretty dirty. Look at those, so we'll get more rinsed up and cleaned out, so your machines have these caps.

You need to take these caps out and clean out that way. I pulled this off just to look at it and it looks like it might get three eights out of that. It's definitely not a quarter-inch line. It's more like 5/16 inside you know, Hoshizaki recommends certain line sizes, but the gallons per minute kind of supersedes that so we'll have to do a test to make sure that this machine is filling up at the right gallons per minute.

I mean it does throttle down. In that little down towards the end, it's hard for you guys to see it there's a little fitting in there and it looks like it kind of chokes down a quarter-inch before comes back up to this size, so we might have a problem with these water lines. Another thing that concerns me is there's a note on this machine that the evaporator was changed less than a year ago. Usually, the only thing that evaporators can change for is and they're deformed or, but if this thing is how to freeze that problem for a long time, that makes me wonder if I've stumbled on to a you know something that people haven't been able to figure out.

This is a new location of me, so we'll see see, there's that note 718 and then there's also a note right here that says inlet valve change, so someone's done a lot of work on this machine, but I pulled this inlet first off, I'm going to verify The numbers on it and I'm going to look in the book to make sure this is the right hand, let down for this machine and then also it's pretty dirty, it's important when you're cleaning these machines, you know you check the inlet valves so and this is What I was talking about in there this one looks pretty clean, so Jose want to inspect those to make sure they're, not grotesque. So that's much better, there's still a slight discoloration right in here, but I'm gon na run some ice machine cleaner thread. I use this brush. This is a Grainger part number Ralph, Victor Frank.

Six. This things are badass they get in the tubes. I can fit it right through that hole and get him and scrape all that crap out of there, and I cleaned up these guys too. I've assembled it and I'm filling it with water.

What I did was I had a completely empty sump and right when the water solenoid valve opened up. I started my stopwatch and we're gon na see how long it takes to fill up that sump to help us figure out our gallons for a minute. As soon as the drain on the right starts pouring water out. We know that that stuff is full because that's the overflow and it's normal for it to fill up so it overflows.

So that's what we want to see. We want to see the waters flowing out of that fight. They took just shy of four minutes. So now we can do a calculation based off of how much water this sum hold I'll, look through the book and find out after I'm all done.

I'm gon na use a sanitizer and you're going to follow the instructions on the sanitizer to sanitize all the surfaces that your hands touched and I ran it through I've, let it run and now I'm gon na go ahead and drain it out. So at this point I started a timer rated for the five-minute mark. I found when their pressures were 47 205 publishes Aki looks at the five-minute mark the total, so we're running right about 80 degrees. So my question weren't too bad.

Another thing is that this unit should have this extension bracket, and it doesn't both of these machines should have this extension breakfast, I'm finding a bunch of problems with it, so we'll have to order up this extension bracket. This is one thing that can cause for yourselves too. Okay, so found another problem. This unit has a 5 gallon sump.

It took 3.5 8 minutes to fill it let's round it up to 4 minutes, five gallons divide about four minutes: we're getting 1.25 gallons per minute. Water delivered to this machine and the requirement on this machine, 2.91 gallons per minute required water pull water flow rate, so the water flow is not good enough, whether or not it's a bad water psyllid valve or it's not water line. Restricting it that's another problem too. That will cause a freeze up, so this machine so far has got an issue with the bin stat.

It needs the extension bracket. It has bad water flow coming into it and then now I'm going to verify if the water valve that's in. It is correct because it has been replaced by the previous company. This was my total cycle.

We had a 27 minute free cycle and then three and a half minute harvest cycle - it doesn't sound unheard up - seems decent. They bought all the ice, so I'm gon na weigh it just to do a production check. I'm not worried about the production of the machine. I believe it's producing fine, it's just a freezeout issue, so we'll see we're gon na keep going.

Okay, it's always very, very important that we make sure we're getting all the arts from Hoshizaki and, if we're not making sure our selves, that the part numbers are correct. The water valve that is in this machine visit je two four eight zero: three three, that watered office for an eight hundred and thirty pound machine. We should have the j2 for 803 too, so the Sunnah have the wrong water bottles. Now I need to call Hoshizaki to find out for sure if the flow rate is wrong for these two, but I would think that it would be because they would, if it was, you know, we'll find out if it's worse or better okay, I ended up having The water valve the correct one and here's what we had before.

We were getting 1.25 gallons per minute out of that water valve. When I changed mine now, I'm getting to point one, two gallons per minute, so that's a lot better. It's still not correct, though we need 2.91 gallons per man, so now that we know we have the right water valve in then we're going to start addressing the water line. Okay, I'm not completing this today.

What I did temporarily until I can get approvals, I'm gon na order, the bin sat in the bin stop bracket and then we'll come back and fix the water line. Issue too, but I adjusted the circuit board to make for a longer defrost to ensure that we get all the ice off of it. I do not ever suggest adjusting a hoshizaki circuit board unless you've consulted the factory or you absolutely know what you're doing yeah. That's.

Why I'm not even going to show it, but you can read the manual it tells you how to do it. So that's what I did for now to ensure that I had a super long defrost to make sure that we melt off in the ice off of this guy, alright guys. So this one was a little bit longer of a video, but I kind of felt like I showed what I needed to show. I tried to cut it down as much as possible hoshizaki ice machines.

They can take a little while to troubleshoot. Okay, you got to follow the steps. This was a freeze up, so you know: freeze ups, take a while themselves just a defrost without ruining the whole machine. If you defrost that ice too fast it'll drop down out of the evaporator and destroy the cube guides and all the parts in the bottom, so you just got to take your time and that's why, in the video I showed how I like to just let the Water pump do the work while adding hot water to the sump, and I feel like you get.

It actually works faster that way, but it's a little bit smoother instead of just melting the ice with the hot water hose. So, as you guys saw it's pretty common, I shouldn't say it's pretty common. I've run into it a few times where freeze up problems end up being installation problems. Okay, this machine never had the right water line from day, one okay, that water line is too small and then, on top of that somewhere along the lines.

The previous company to me installed the wrong water inlet valve on this machine so that you know affected the water flow coming into the machine. Also - and you guys saw - I had the water valve, so I went ahead and replaced that, but I'm gon na have to get a plumber in there to change that angle, stop valve coming out of the wall and then we'll correct the water line. Sighs going to the machine, okay also recommending, like I said in the video that we replace the bin thermostat okay, and we also put that extension bracket that I pointed out from the book on to that bin thermostat and we'll put that extension bracket on the left Side machine too, it's very important that you put those extension brackets on there because they've since realized that when you drop, you know that whole evaporator full of ice on top of there, that the ice can still back up into the machine. And if you guys don't understand that bin thermostat is essentially just a temperature controller and when the ice gets close enough to it, it opens and shuts the Machine off.

Okay, so bad bin thermostat, bad water, inlet valve water line sized incorrectly coming into the machine. All of those things led up to this thing, freezing up the way that it had, and I bet you anything - I wasn't the service company that changed that evaporator, but I bet you anything that that evaporator didn't need to be changed in the first place. Had the machine had the right size, water line coming into it, you'd be surprised what you know a little bit of a size. You know how much an incorrectly sized water line coming into that machine will affect these Hoshizaki machines.

They really rely on that fresh water. Coming in to help break that vacuum that the ice cubes get stuck to the evaporator, basically, okay, so yeah, that's pretty much it I'll try to get some follow-up video. When I do the repairs on the machine, but you know I felt like I showed what I needed to show on this - and hopefully you guys got something from it. Okay, really appreciate you guys taking the time to watch my videos right now.

You should see some other channels popping up. I suggest you give those channels a shot. Leave me some feedback down in the comments, and we will see you guys on the next one. Okay, thanks a lot.
