Question about Hobart AM14-253 Free-standing Dishwasher

1 Answer

Hot water blasting out of relief at top right of hot water input

This AM14 has all kinds of special plumbing that we dont fully understand. It is now out of service because the water leak caused great damage to the floor. We need some specs for all the special plumbing that includes a water heater with a gauge on the feed line that rises and comes in the top with some kind of silver topped relief valve that also has an electric valve. In addition the exit water is plumbed in plastic and there is another valve that controls hot water injectged into the exit water to prevent the plastic pipes from deforming or "melting". We called Hobart out and the quoted $800 - they didnt spec what was wrong. Can we get the specs for the installation and the sequence of things that are supposed to happen when we fire it up so that perhaps we can make a better description of the problem. We dont have $800 of a unit that is only years old.

Sounds like you have a booster heater. Hatco maybe or one built on the machine next to the pump motor.? the valves on top the chrome one is a vacuum breaker. easy to put 15.00 kit in. the electric one just fills and rinse gauge just tell pressure . Did a valve on the booster heater leak or its tank maybe. The AM14 is very simple crect temp and presure water going in and your in business if the machine is ok. Boosters have a saftey valve that will go pad and they let water out. just like all home water heaters do. they screw into the tank. yours should have a line to the drain. so if it does leak it goes down the drain not on the floor. all the things you describe on the upper right of your sishwasher are just the nopremal fill and rinse. both the crome thing and the electric have kits that can be put in. I would call hobart and say sendf me a itamized estment of repair so you know what your paying for. with part discritions and numbers and prices. Or call me LOL kidding

WIRLPOOL DISHWASHER COLD WATER CLEAN ONLY!!!


HI Nick- the element in the dishwasher dries the dishes and sometimes boosts the heat of the water. Your water should come in already hot, so the problem is either your hot water heater or that the plumbing line was switched to cold by mistake. Or that people are bathing, laundering, etc. and using all available hot water right before you run the dishwasher.

Can i connect a dishwasher to the hot water pipe??


In my opinion you always connect to the hot water unless there's some compelling reason not to like your dishwasher's manual says to connect to cold. Your dishwasher will heat up whatever water you have connected it to, but since you have a tank of preheated water already sitting in your water heater you should use that.

The "resin in the water softener" example, I think, makes no sense since your dishwasher will heat up the water to something like 160 degrees Fahrenheit no matter if the input is cold or hot...

Whirlpool Dishwasher Problem


the dishwasher will probably heat the water the rest of the way for you. depending on the specs and features.
hot water is not likely an issue with the dishwasher itself.
you could have cold water plumbed to the unit by mistake.
also, it could be that it is not fully pumping out, and the water going in is mixing with water in the sump.
try running it for few minutes and then pump it out. start a new cycle and see if you are getting hot water. if not, then at try to confirm that the unit is heating the water on its own. run it for about half a cycle and check the water temp again.
you do need hot water to clean in most units.
for certain this is a plumbing problem that is delivering cold water. and if its not heating, make sure that it should be per manufacturers specs, and call for repairs if its not heating the water.
good luck
