HOT OR COLD WATER IS NOT BEING PUSHED THROUGH THE PUMP

What kind of faucet are you using? Sounds like a mixing problem inside the faucet.

Is it both hot and cold with the leak? These are replaceable!

it sounds like either your head gasket has gone or your water pump is not working correctly. try taking off your radiator / expansion tank cap and turning over engine, if the water is pushed out of the tank your engine is pressurising, a sign of blown head gasket. to check the water pump is not as easy. check to see if the radiator is getting hot and fan cutting in.

We typically service Hoshizaki, but you may not be getting water into the resivior. Depending on model, you may need to remove bottle and probe and check the silicone seal, reseal and re attach. Also be sure that hoses are connected and fully pushed into the connectors. And of course make sure you have a water supply. Could take up to an hour for water to re chill again. Hope this helps.

Newer machines know the water temperature. It will mix hot water even on a cold setting if the incoming water is too cold. Detergents need a temperature of at least 60 to activate.This will only happen in the winter usually.

This is could be because the system is set up to use the cold water line as the return to the HWH.

Hot water recirculation systems generally consist of a pump, an integrated electronic controller, and a zone valve. When the activation button is pushed, or when another type of control turns the system on, the pump starts recirculating cooled water that's been sitting in the hot water line and sends it back to the water heater through the cold water line.

If you would like..Google "hot water re-circulation theory"...it further explains this senario.

You will have to be specific about what problem the pump is having. It seems to pump ok for everything else. Could the hot solenoid be shorting and sending electricity down the water to bother the pump? Solenoids are not real expensive, try a new one.

hi did you run a seperate cold water supply from the storage tank to the shower pump & also a seperate hot supply from the hot water cylinder, it sounds as though the cold water is crossing into the hot service & pushing its way up to the tank as its the only way it can go, sounds as though the cold water connection to the shower is not tank fed & possibly directly off the water main.?

make sure the tub is pushed back , not leaning foward. this fills from back of tub possible splashing on and over the tub rim, anorhersource of leak could be from pump assy removing front cover and lookng at pump will tell (if its been leakin its quite obvious)
