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

Master temp 400 2 yr old bad heat exchanger??

i dont blame you for your frustration!! i have hadseveral customers who had great water chemistry and had the heat exchanger fail. if you have a salt water pool, you should have been advised to purchase a heater with a cupro nickel heat exchanger instead of just a copper one. otherwise since ur chemistry was spot on, then you unfortunatly purchased a bad unit
