Why doesn't the water cooler cool water 

Lol, Here I came looking for a solution...

Looking forward to seeing your final diagnoses mr gray.

It's a heat sink, air is pulled through fins on a block of steel or preferably aluminum. Another student brought in a rather large wine cooler last year with this setup. I recognized it right away as I have built PCs for years. The issue with his was dust and grime built up in the fins but yours looks pretty clean. Other issues with these can be a bad fan or the block not being seated correctly. Yay! I think I finally answered one of these!

It's a thermoelectric cooler, using the peltier effect. When current is applied to the peltier junction one side gets hot, and the other gets cold. The hot side is cooled by the heatsink and the cold side cools the water. Maybe the power supply is bad or the peltier junction has a defect?

He sounds like Hank hill 😎

So, if there is a series of videos on this,, maybe point us in the direction of the next video that shows how to fix the problem.

This is the first time seeing you asking us the question how it works lol. You're very old school, this is a simple lame water cooler unit using a "peltier cooler".

I'm on the edge of my seat with this one!! Nice one GFM. :D

Give it a kick in the circuit board, and will star working. After that you have to take down this F video

The Peltier module is probably broken, just replace it and it should work fine

Good

Lmfao i walked in on a bunch of fuckin water fountain conesuers bein like "ooooo yes i'm on the edge of my seat with this one!! Nice one GFM. :D" Like wtf i was looking for water cooling components for a pc and i walked in on a bunch of old men xD

Try cleaning the fan, it happened to my cooler and i took out the fan, clean it, oil it an it works like new

Hello sir, my water cooler is a bottom load whirlpool dispenser. It is no longer pulling water and light signal indicates the bottle is empty when it is full. HELP! Could you do a video about this?

Your fan was not running ....needs to run to let the peltier effect do it's job

I would work backwards starting at why the fan is not running,

It looks like a thermoelectric...is the fan running?

I think it could be a powers supply issue and possibly the control board? Not use to these machines. Nice video GFM, thanks for doing these.

I guess I'm not going to learn how to fix my water cooler here 😒

I'm guessing something with the fan not running.... not sure if the fan cycles on and off and only runs when cooling is called for ???? Fuse or Fuse Link ? Does the water heater also use the evap heat pump system or is it electrical resistance heating ? Great Videos by the way.. have learned much ! Thank you Grayfurnaceman !

You need to replace the cooling fan.

the fan isn't working need to replace the fan. i had the same problem.i sprayed some wd40 on it until it was able to turn... then it cooled for a time...until i really needed to replace the fan. it electronically cools the water via conduction system of the radiator behind the fan. the fan takes the heat away... thus cooling the water.. once you fixed the fan it cools the water. try replacing it with a more heavy duty brand.

I fixed mine no problem took me 2 hours lol

repair the fan ..

The fans not working

HANK HILL """!!!!???

I have a question , why doesn't my water heat ?

its a peltier cooler unit

Mine freezes whenever I plug it in.

for real ??

Looks like a thermo electric cooler to me.

Wow man, seriously? Wtf did I just watch?

what wrong with u i though u give tutorial about ds

Catastrophically horrible waste of several minutes of my life, on the bright side, I wasn't using data, I was on the home computer.....sigh.....

A minute and forty two seconds wasted…..

Hahahahaha... Your problem is very easy to solve... Stop being cheap and buy a new one.
