So today we've got a Hoshizaki problem upon a 2 beep safety limit, defrost backup, timer right inside of here, its back corner. It says alarm reset right there. Now I push the reset button and we're gon na. Let the Machine started cycle over again and we're gon na watch everything and see what happens.

One thing I don't like that's going in the red as far as water pressure goes, so that's not good. What do you know about we're gon na go through our checklist to figure out what caused this to freeze up, but the water pressure already looks like a problem in me any minute. If it's not our might already be late, so we're gon na defrost this defrost it we're gon na, go ahead and put it into the Queen and then go ahead and turn the cleaning valve slightly. What that does is that forces water from the water pump up into the water distribution hose? So you have a fresh water distribution line right here and then you have a research line of the pump.

So when I turn that see that she going here, it forces the water, normally the water sits there and stops it's simply there for cleaning, but it will help in the defrosting process. So we open it up so now bringing water in water inland rails to help the defrost this balcony and then I'm gon na grab a water hose, get some hot water in here and help this process along. I wouldn't be surprised. Oh, please break the tube guys because we're gon na how much ice is coming down right now a lot of weight.

Thank you guys. So this is just my method. The way that I like to do it, I feel, like the water pumps, helping me - and I just put hot water into the ice bath down here and the water pumps, helping to basically circulate that hot water. So this is how I roll with it.

Some people choose to defrost it from the top. I've done that before each their own that I'm gon na be coming down. You don't want to come down mm as well, because you'll see it comes down and it kicks back to you guys a lot of weight. I was trying to do it.

You don't want to. Basically you know put it up here, all the way up here and then shave off big chunks at a time, because then it'll fall down really hard. Some runs a little bit ice machine, cleaner, spare, real, quick scaled-up just before I did anything else, and while I'm waiting for that to finish up, I'm gon na run a leak detector across this classroom right now, just because it looks like it could be leaking. Maybe one more shot nope, it's leaking underneath the compressor.

If you need to drain these things on the quick if the bin is completely empty, like in my case, and I want to drain out all the cleaner, just pull off the pump hose hold, it very carefully make sure all the clamps on and then turn the Pump on once i've drained all the water out. I filled it back up with hot water again be careful. I didn't put this clamp back on the pump option, william the case, so you got to be ready for that. But i'm gon na go to turn the pump back on, circulate it and then drain it again.

We're just getting a hot water running through the machine or just rinsing out of the cleaner. All right go to your cleaning valve and open it back up again just give the Machine a good rinse. Will he just want more time after this and then we'll run a sanitizer through it and maybe he'll be ready to make ice? Okay, we're all clean now! So now what we're gon na do, because when I first walked up, I saw that water pump or that water filter went down into the red when a machine was filling. What I'm gon na do is I'm going to time this.

This is a five gallon sump on this particular model. You have to pay attention your model, okay, but this one has a five gallon sump, so I'm gon na start my stopwatch and the moment that the water overflows do that overflow down there and it starts coming out. The train is when we've hit that five gallons so by me timing. It I'm able to see the gallons per minute at which this machine is spilling okay, so I'm gon na start that right now and I'll show you guys the results.

Okay, so we're gon na flip this on on the moment that this water valve turns on we're going to start our stopwatch go, and it start up a stopwatch put there. The black needle is pegging in the red. What we're gon na do is we're gon na keep timing until water comes out that one that's drifting right now, so as soon as it starts coming out of that, we know we're at the five gallon mark. That's it there's our time.

So now we can do the math, it's actually 250, because I pushed the wrong button. Okay, so my firm the machine on currently it starts out at harvest until this thermistor senses a certain temperature that a timer happens inside the board. It is turned on right now into the pre cycling, so when it goes out, a lot has defrost and a lot of fun turns on we're gon na get started on our soft launch. We're gon na wait until the five minute mark.

Then we're going to record the freshers coaches Aki publishes the refrigerant pressures about five minutes into the pre cycle. That's what we're waiting for the five-minute mark once it hits the 5-minute mark and follow all the data. Take the pressures you look at the water town, the air temp and then you know fifty six and two twenty two so I'll write that down here's a little trick. I like to show people if you're, having a hard time with an expansion da but you're, worried about an expansion valve, do a temperature comparison.

Look at my two temperature for him. We want to put them approximate in about the same place. Both those TX bees have the same load on them. Essentially she be able to clamp those there.

Temperatures should be within a degree or so of each other. It's pretty good. I don't see a problem with that. I'm just confirming the TX peas are working properly.

So our flow rate we're working with a km 1340 mrh so that this one right here can 1340. So we need 2 point 1, 1 gallons per minute, and I calculated us five gallons divided by two point: five one equals one point: nine, nine gallons per minute that doesn't sound of that, I'm not going to fault it. Just for that we'll see we're gon na keep the check and everything else out the pressure and pressures a little funky on the low pressure side. They were a little high, but the head pressure was in line.

That's why I was checking those expansion valves to see if I was flooding everything's looking good so far, so we just cycle, then you will harvest and I push lap. So that's my freeze time now we're gon na keep letting in count, though, because we want to get the harvest time to to get our total cycle time and that'll allow us to build at the same time in a way happening here. We're currently waiting for the water pump to turn back on to end the harvest. That is Sigma with the harvested English, but what's actually happening is the machine is filling or feeding the hot gas, and now hot gas fell right back there inclusive operator and is monitoring the temperature on once that thermistor sensed it then it knew it was time to End the harvest and I'm going to and stop so we have a 31 minute free cycle and on three point four minutes so now we're checking the production.

This is my total batch weight and put it in the pan that I caught it all in 30, pounds. Eight ounces now we're gon na dump the ice out and then a relay the pan. So that way we know exactly how much ice we used. Yes, and now we weigh the pan empty and we subtract a 2 and that's our total batch weight.

Okay, so in the book it tells you how to do a production check, but essentially you're gon na take your total cycle time. 34 minutes. That's the harvest, plus the freeze, okay, you're gon na take 1440. That's the total minutes in a day you're going to divide that by 34, which is the total time it took to make your cycle is that equals out to be 42 cycles per day, then you're gon na take your batch wait.

27 pounds times the 42 cycles per day - and I come out with this machine - is right now producing eleven hundred and forty-three pounds per day, and it is a thirteen hundred and forty pound machine. So that's eleven hundred pounds in 24 hours and it's rated at thirteen. Forty, it doesn't sound horrible, but we do know that this machine is low on charge. Okay, so so far this is the production check.

That's the water check. The next thing I'm going to do is I'm going to check the bin thermostat to see if that's working properly so I'll show you guys that all right, so we're gon na do a production. I mean a Ben thermostat test. So this is our Ben thermostat right here: okay and essentially we're gon na take ice and we're gon na put it up on the Ben thermostat we're going to time how long it takes to turn the machine on and off.

Okay, I'm essentially going through a Hoshizaki freeze up checklist and I'll show you that's that I'm just doing it in my head, the steps, but so we're gon na test that right now so to test that we're going to put the moon the unit into a wash Cycle so just the water pump is running. It's going to do that water puppets running we're gon na grab a scoop of ice. I ignore the first time so ignore the first cycle and then launch it from that point forward. So we're gon na wait for the shutoff sign there.

Okay, so we just shut off right now. So now do your time, with your warm hand, took three seconds to turn on twenty-nine seconds. That's not good! Okay! So this was a service call on a hoshizaki ice machine that was not working properly. When I arrived, I found that the right-side ice machine was actually offed on a safety limit.

Okay on the Hoshizaki ice machines, they have an audible safety limit. This one was off on a 2 beep safety. What I did was, I went through the machine and I just you know, went through it with a fine-tooth comb and found out that the machine was actually frozen up. That was the first thing once it was frozen up.

We just basically go through a checklist that Hoshizaki gives you called a freeze up checklist. Ok, I kind of know everything in my head, but if you guys don't know what that freeze-up checklist includes, what you want to do is open up your Hoshizaki book and in the front of it, it'll tell you, you know, freeze up checklist this page and then Just go through the items one by one; ok, so I just kind of did like a cliff notes version for you guys just kind of shortened it down, but essentially we did a water flow test. Ok, we tested the gallons per minute. How long it took the machine to fill up with water? We did a production test on the machine.

We did. A bin thermostat test on the machine also found that the compressor was really rusted out and leaking on the bottom. So we did a leak check on it and you know we just went through everything. Ok, I give some tips in here on how to you know, defrost the machines and my method.

What the fastest way, I think, is that's not necessarily the only way to defrost these machines, other people have their ways and they work just fine. Ok. This is just the way that I like to do it important. One, though, is to note that water water test, ok to see what the gallons per minute of water flow is coming into that machine, because the gallons per minute really is important when that machine is operating properly.

Now I don't know if you guys caught it, but another thing to always pay attention to is the size of the water lines coming into the machine. You'll start to notice a trend that a lot of people do not follow what the manufacturers say. If you open up the Hoshizaki book, they will actually tell you what they recommend for water line. Sides is coming into that machine being that that was a 1,300 pound machine.

I off the top of my head. I don't think I know it was a 3/8 water, inlet and a 3/8. I don't think is big enough for a 1,300 pound machine. Ok, so that will also affect the water flow coming into the machine, but also like you guys saw to there water filters were actually getting pretty dirty too.

So I told the customer to go ahead and have they use eco lab to to change their water filter. So I told him to go and have them come out there and replace the water filters too. Now I went through like a whole checklist, because I always look at the big picture, like I always say: okay, but this customer after I reported everything to them. They actually decided to replace the entire machine.

They do not want to repair it. They're gon na go back in there. They're actually gon na replace both of their ice machines and put two brand new machines in there on one bin, okay and eliminate. They really do have a bad setup because that location is located out in the desert and one of those machines is a remote and then one of them is self-contained and it's just hideously hot in front of that ice machine.

And it's wintertime right now. But it's because of the self-contained machine, it's just researching the heat and it's just kind of silly. So we're gon na get to more than likely manats walk, quiet, cube machines in there that'll be remote remoted onto the roof, and everything will be good after that. Okay, so you know thanks again guys for taking the time to watch this video.

I really really appreciate it popping up right now with some other channels that I recommend you guys check out and other than that. I will see you guys on the next one. Okay thanks a lot.
