Hobart AM-14 water temperature not maintained

Helping a business owner with a Hobart AM-14 dishwasher with electric heat but without a booster heater. With normal water level but between wash cycles (dishwasher idle), should the water temperature be automatically maintained? The heater contactor is energized only during the (short) wash cycle, but is deenergized at other times. This allows the water temperature to become too low to be effective. Thanks.....Lee

The AM14 when filled, will control the wash heat on the thermostat and high limit controls, putting power to the wash heat contactor. I believe it is 2CON. This circuit is not timer cycle dependant.
There are two types of control board form the AM14. The older has a black metal heat sink in the center, You set the wash set point by holding the wash heat button on the board. This will cause the display to flash with the set point. Turn the trim pot on the board, near the top to adjust.
There are a variety of versions for control voltages. Most are 24v ac. Check your schematic inside the control box, or look at the spec of 2CON for the coil voltage. Put a meter on 2CON coil to monitor the control. If power remains on the coil but the contactor drops out, you have a coil that is opening with heat. If the power drops prior to set point, trace the loss of power through the controls.

I have a LXiC Hobart dishmachine I do not want to use Sanitizer because my hot water is very hot. How do you disable the sanitizer pump and alarm? H.


Do you realize that to sanitize with hot water alone requires 180 degree F water? I am a hobart technician and I've never seen any business or residence with hot water anywhere near that. Residential hot water is generally approx. 120, Commercial locations generally use approx. 140, but never near 180 (tap water that hot would be a severe safety problem). Hobart LXIH machines use a built in booster heater to boost the temperature of the incoming hot water up to the required 180 deg.

Hobart LXIH stuck in Wash mode after running multiple loads. Shutting off breaker for several hours fixes problem until multiple loads have been run again and then it is once more stuck in Wash mode.


How long does it stay in the wash cycle? Indefinitely? Does the display continuously show "WASH"?. If it stays in the wash cycle indefinitely (i.e. continuously shows "WASH" for significantly beyond approx. 3 minutes), it's probably a control board malfunction. If it continues to wash after the "WASH" indicator goes out, it could be a shorted wash motor relay on the relay board or a fauly control board.

If the internal rinse water booster heater doesn't reach it's programmed setpoint temperature in time, the dishwasher will run an extended wash cycle to give the booster heater more time to finish heating the rinse water. If this is what's happening, the wash cycle would last approximately 3 minutes, then it would rinse regardless of whether the booster heater has finished heating or not.

The booster temperature thermistor may be bad, giving a false booster temperature reading, causing an extended wash cycle as described above. The booster heater elements or contactor may be bad, preventing the booster heater from heating and reaching proper temperature, also causing the same extended wash cycle to give the booster more time to heat.

Do all Hobart dishwashers have a element in them for wash water and rinse water


All Hobart dishwashers will have a wash tank heating element, but the rinse water is not heated by the dishwasher, unless it has a built-in booster heater. Usually a separate booster heater is used to heat rinse water to 180-190 deg. F for hot water sanitation.

Verifying breaker rating of AM-14


Commercial dishwashers don't take it for granted that the hot water is hot enough to sanitize. And, they know restaurants need to turn dishes.

So there is enough heat to make sure warm water heats up quickly to sanitizing temperatures.

Hobart lx 18 warewasher what hatco booster heater product compatable with it


The answer to this question will be based on the incoming water temperature that is supplied to the booster heater. The standard sizing for a booster heater is based off of a 40 degree F rise (140 degree F incoming water temperature) or a 70 degree F rise (110 degree F incoming water temperature). For a 40 degree F rise, a Hatco model C-5, S-5, or PMG-60 will supply the needed amount of rinse water for the LX-18 Hobart dishwasher. A 70 degree F rise would require a Hatco model C-9, S-9, or PMG-60 to supply the same Hobart model number.
