Oh! So even though my volt meter was reading the correct voltage, the rotary dial still could’ve been the problem? I don’t know if I have a way to read Amps?

This is the first time I’ve had it happen if you can believe that. And this switch was the original one!

There are no check valves before the hot and cold water valves - just one after the tank on the hose feeding the pump. I think you are 100% right about the hot side solenoid not opening all the way. I replaced it 3 times and it didn’t change anything so I feel it has to be electric. What’s weird...

Sorry, I meant to reply directly to you but I think I did it wrong: lol! My tankless heaters can only put out 3.5 gallons per minute. They have been inexpensive to run and been bullet proof for 26 years. You gotta love Japanese made products. There is one check valve after the tank and before...

Shoot! I should’ve taken a picture while I was there. I’ll screen shot a picture from my cameras, but the cameras in the equipment room are not very good quality so I don’t know if you’ll be able to see much. It’s Futura/Specialty Equipment. This location was built in 2003 (my newest) and...

The only solenoid I have is right before the tank. It’s two sided, one opens for hot and one opens for cold. So there is no solenoid between the tank and the pump. If all the rotary dial does is pull in the contactor, do you know what sends power to each side of the solenoid to open depending on...

I love all this discussion, it’s helping my brain work. My self serve bays each have a single tank/float each that handles both hot and cold water. Do you think the float could malfunction just on hot but work fine for cold? I’m willing to try anything, including putting in a new float - I just...

I didn’t switch the hose out, but I did switch to hoses and a water heater from an adjacent bay that is working fine and the same starving issue happened. I decided to replace the rotary dial tonight because I swear the problem is electrical. It’s definitely not the dole valve so it’s got to be...

It followed the hot water. It’s Fed by a VFD Grundfos pump out of a 300 gallon holding tank. That pump/tank feed all the bays and only the hot water on this one bay is acting stupid. I went back tonight and changed the rotary dial. I swear it has to be electrical.

In my 26 years running self serve car washes, 99% of the time these symptoms have been from a blown low pressure seal. This is the easiest thing you will replace on a Cat pump. Look to see if there is a water dripping from underneath the front of the pump - usually it will drip after someone has...

Ok guys, I am stumped. I have run the same self serve equipment in all of my car washes the last 26 years, and usually the mechanical issues are pretty straight forward. I’ve got one that is driving me nuts. One of my bays is intermittently starving on the hot water option, not on cold. There is...

I did reuse all the old fittings. It possible one it cracked but I REALY wish if that were the case that it would at least have a teeny drip or something. I’m not sure where to begin when it comes to trying to sleuth it. Should I replace all the fittings? Shouldn’t be any foreign objects in the...

Oh! Well I didn’t try taking it out of the equation all together. I’ll remove it and see if it smooths out.

I just reread your original reply and I think I didn’t read it right😁. Did you ever end up solving the problem? It sounds like yours was much worse than ours, but maybe they are having the same problem.
