Alde Hot water TaB 320 S.

My hot water goes cold when the water pump is on. Why is this? New Tab owner.  Trying to figure this thing out before I actually camp.

What trailer model and year do you have?  Is it new new or did you buy it from another owner?

Here is the mixing valve thread, which is sometimes the issue on a new trailer.  Look it over, and there will be ideas.  But, your model and year will be important to narrow things down for you.

The first link here asks about where to find the mixing valve.  If you looked at the thread I posted earlier, you should have an idea what to look for.  Easy to spot.

On our 2021, a little yellow tag was attached to the sink faucet saying that the Alde was set to the lowest temperature setting. I've followed the very helpful instructions here to recalibrate the mixing knob. For me, I ended up moving the knob about 3-4 "clicks".

The reset of the mixing valve knob worked. Thanks to all.
