Primo Water Dispenser - Cold Water Failing To Dispense - Freezing Reservoir Fix

Primo Water Dispenser cold water stopped dispensing. Reservoir was freezing causing cold water not to dispense. No thermostat on the unit but it does have a temperature sensor. Replaced the temperature sensor for a $2.00 and working again. Easy, inexpensive fix.
Here is the part at Amazon:
DROK 10K Temperature Sensor Probe, 5pcs 1 Meter Waterproof Temp Sensor Probe, Stainless Steel 3950 NTC Temp Sensor Probe, Digital Temperature Transmitter Extension Cable

I’m convinced these units are designed to fail after 1 year. Every primo I’ve owned does this and you’re the first person to have an answer. Feels like class action material.

I'm having the exact same issue after a year. No cold water dispensing but the hot water is fine. Could all just be because of a temperature sensor?

[@zzotto21]

Yes. Open it up and check to see if the reservoir is frozen. Or…. Turn it off for a day and see if the water starts to flow. Pretty easy to figure out if it is the sensor. And good luck!

I’m so glad that this was a sub $20 fix. I didn’t want to go out and buy another $200+ water dispenser. You saved me money! Thank you for posting and being very informative!

[@Nicole-dv9jo]

First, my dispenser started freezing water, so I turned off the cold water switch on the back panel overnight. But after a couple of months, the green light started flashing and the water stopped dispensing at all. I realized the problem was with the thermostat. All the videos on KZbin aren't about this problem. Only your video helped me to fix it. You saved me $250+ (Primo Smart Touch). Very informative video. Thank you so much!❤

[@zzotto21]

You are very welcome! Glad it helped you out.

[@KingIrvXL]

Did all the water stop dispensing or just the cold or got? My hot dispenses but the cold won’t . I took the lid off and the button works it’s just no water flow for the cold

[@KingIrvXL]

I’m thinking maybe the cold gets too cold and freeze because of the broken thermostat. I’m going to unplug it for a few hours then try the water again. If it works it’s the thermostat

[@zzotto21]

If you open the lid to the tank you may not realize that the water is frozen on the bottom of the tank. Mine was and the ice was so clear I could not tell. I put my hand down and tried to touch the bottom of the tank but. There was solid, crystal clear ICE! And the ice was what was preventing the cold water from flowing. Thank you for the comments.

[@zzotto21]

And no thermostat. My unit has the thermal sensor, plugged into the control board.

[@nohardfelnz]

Wow...Thank you...please note, my Avalon A14 wayer dispensor had the same issue, I called support they basically said buy a new one....well this video was the saving grace! My water dispensor is back up and running for less that $10 vs buying a new dispensor for $300. Thank you teo thumbs up!

[@zzotto21]

I am glad it worked for you! Thanks for the comment.

[@Michael-dz9hk]

Thank you for the video. It was very helpful locating the temperature probe. Excellent explanation. The styrofoam around the tank is split into halves and the halves are secured by tape. Once the tape is cut, you can kind of separate the halves enough to reach the probe. The way I accessed it was by removing the grill, top back plastic panel and removed the stainless steel box located on the right rear side. I removed the connections on the circuit board. Take of picture of the connections on the board inside the box, so you know where to reconnect them at. Now you are able to get in to where the probes are at more freely. I removed the probe first before ordering the probes from Amazon. I just wanted to make sure I could get it out first before spending money on the probes.

[@zzotto21]

Thank you for letting us know how you did it! Great job.

[@jj78rcclub]

Did you have to remove the front panel?

[@itsamk18-ish]

Thank you for this! I cut the tape on the foam and i could shimmy it off enough to get to the probe then it just popped back together. I was about ready to figure out a new solution for cold water because primo just wants people to buy new units,luckily there’s guys like you out here showing people how to do stuff 🤘🤘🤘 There is another fix for this by using a 10A.Inkbird ITC-308 Digital temp control. It’s a little easier to do for someone not wanting to mess with wires. You just drill a hold in the lid of the reservoir to drop the probe into, set your temp and once it hits the temp it shuts power off to the unit. It’s more expensive and not as good of a fix but it’s another option.

[@zzotto21]

Thank you for the comment and the second fix! Hopefully, both of ours solutions will help others save a few bucks and get cold water.

[@Speedyfast66]

This video was perfect. Saved me from buying a new machine. I found them on Amazon just as he explained and replaced it. Once the ice was melted inside, the machine worked just as it should. Perfect temp waters, and going strong now even a week later. Thanks for your video 🙏🏼

I can also confirm this works. I gave up on the styrofoam and pulled out the metal thing that was filled with a white stickt substance. I'll just replace with insulation, the blue clip couldn't be replaced with the white clip from amazon so i also had to splice it like OP. everything went back to normal. Many thanks, Primo really did shit the bed.

Great information, I saw other video where the guy just unplugged the unit until ice melted but never mentioned why that happened. So as your water dispenser, mine does not have temperature regulator even is a different model. In other video the guy tested the thermostat sensor with an ohm's meter noticing the resistance failed. So, it makes a lot of sense to buy a new sensor and avoid all that checking. Thanks for sharing the sensor information.

[@zzotto21]

You are welcome. I wish I could have found just one sensor instead of five. It would have been great to say I fixed it for $2.00! Hope you are successful with the repair. Let us know?

[@KingIrvXL]

What model is yours? Is it the 601088? And where is the sensor for yours?

[@zzotto21]

King: My model is 601256. The sensor runs from the control board (blue plug, plugged into the board) and runs to the lower right, low, of the tank, as you are looking at it from the back. Look for the two (2) black wires going into the tank area, through the styrofoam insulation. And thank you for your question.

Hi Robert. It's wonderful that I happened to view your clip of possible solution for my same issue. My water col/cool/hot dispenser had this same problem, on the cold side. I unplugged over night, then plugged back. Cold water flows again. But it only worked for a few days. Then cold water stop flowing, that was ok, because I needed hot water more often. But then cool, hot water also not flowing. My unit is only 18 months old. If, it's over 2-3 years, I probably would replace without troubleshooting. But I liked this unit because hot/cool/cold all flow at the same central point. I dont like hot flows on hot side, cold flows on cold side. So, I started search you tube. Few other fixes didn't make sense, until I found your clip. It make sense. I opened op the unit, and felt ice outside the water holder. I unplugged overnight, now hot/cold side flows again. So, I ordered the same temperature sensor you posted. Let's wait to see it this will permanent fix the water flow, which I feel it will because it made sense. This sensor stopped working, thus it continues making cold water, and unknowingly so cold, it becomes ice. and thus no water flow. I'll bookmarked this clip, and will come beack for my update after I replaced this tem sensor.

[@zzotto21]

Tony: thanks for the comment! I hope the fix works for you. Not sure if you read the other comments but someone indicated that the white grease substance was probably “thermal paste.” I would order a small tube of that and put it on the new sensor before inserting into the hole and then pack the hole with some of the thermal paste before putting the styrofoam insulation back on. Good luck with the repair and please let us know if it worked for you. Bob

Suggest using a sharp box cutter to cut through Styrofoam insulation, but otherwise, you can use any type of good insulation to cover missing pieces and tape over as you did. Also, did you take off the side panel for better access to the probe? Splice job will work for that job. You fixed it. Nice job. On mine, so far so good after about 2 years

[@zzotto21]

Hello! I am sorry your dispenser is not working but I have no idea about your make/model. Remember, I am just some guy tired of things breaking! What I would do if I were you is open your dispenser up, after unplugging it of course, and looking for wires that go to the holding tank. And look for 2 wires that run from the control board to the side and down on the tank. Then, explore! See if you can open up the insulation in the area where the wires go and then feel around. You may be able to pull on the wires and see if a thermal sensor comes out. You will know what it is because it will have what looks like a stainless steel end - sort of like the part of a thermometer that goes into your mouth - only larger. And the other problem will be what thermal sensor do you need, if you do find it. I am not sure the one I used will work for you, but who know? Anyway, you may want to explore before throwing it out. And do not forget the thermal paste, if you do find the thermal sensor and will try to replace it. Thanks for your comment and good luck!

Since there are two wires coming from the connector, how did you know which wire to splice with.

[@zzotto21]

Joe: I cut the entire sensor off. I unplugged the water dispenser before doing any of this, of course. Get the sensor out of the hole. About 3-4 inches from the sensor, cut both wires going to the actual sensor - not the connector side. I left the connector of the original sensor plugged into the board in the water dispenser. Then I cut the connector off the new sensor, about 3-4” from the connector side. I did this so I had plenty of wire on both the old sensor and on the new sensor. Actually, I then had way too much wire but that makes it easier to splice the new sensor onto the old sensor’s wires that is still connected to the board. Then I stripped the 2 wires on the new sensor and I stripped the 2 wires from the old sensor (being still connected to the board), and then I simply connected one at a time, taped each wire with electrical tape, then taped both together. 2 wires to 2 wires.
