SOURCE: Indesit dishwasher overfilling

There are two ways that dishwashers generally fill. One is a float inside the tub, the second is a tube which fills with water, loops and goes to a pressure switch below the machine. That switch is usually about 1.5 inches in diameter, two wires and a small hose going to it. The float witch is found below the float in the motor area. With the float, sometimes they jam with too much old detergent or food goo. Clean out. Both can have the switch weld closed. Change the switch in either case. Since the unit is not filling with the power off, I'm going to guess the water solenoid is okay.

This is probably a control board failure, which should be replaced by someone familiar with them.
If you are handy, you can do it yourself.
If you need assistance, let me know.

$0. Clean the probes. Two in back right corner. Two under the front screen. Use a green scrubby.

If the problem persists, check where the water comes into the machine. There is a screen on the hose that clogs up and starves the machine for water.

SOURCE: Hobart LX 30 P2 Error and unit overflowing!

Hi drogers77,

I'm not a Hobart technician, but here what I founded in my manual for the LX30 error message:

LX18 / LX30 display shows E0, E2, E3 or E4

1. Low water pressure - check for clogged hose strainer; check that site water pressure meets minimum flow pressures.

2. Make sure probes are clean

3. No water pressure - main water supply valves may not be working

4. Drain valve open - turn machine OFF to drain machine, then ON. Repeat twice (this assists in clearing any drain valve obstructions). Wait for machine to reach READY mode and press WASH. Slowly open door several seconds later and note water level. Close door; 30 seconds later, open door slowly and check that water level is the same as it was. If not, repeat the OFF-ON procedure. If problem persists, call your local Hobart Service Office.

5. Delime machine.

Hope it will help you.

SOURCE: Water overflows from dishwasher.

The most common cause of a Sears Kenmore dishwasher over flowing is a fail "float" switch that detects when the water has reached the proper level.
If you want more directions, please post back here and we will take the next steps. OK?

Hobart lx18h Booster does not heat up. machine powers up and will wash thouugh all cycles but the booster does not heat up water.


There are one or two hi-limit relays on the booster. One is on the front and if there is a second one, it is on the right hand side as you face the front of the unit. They are both manully have to be reset if tripped. Check them and also the booster's contacter

I have a hobart lx18 and when i plugged it in, it started smoking


I have to asume the wiring connections had not changed since it last worked.
There are three versions. LX18, LX18C and LX18H.
Inspect the relay board for damage. The connections can come loose and melt relays.
It could also be the wash sump tank heater or the booster heater if it's an H. The other two only have a sump heater. If you power it on, and have no water in it's tanks, the elements can glow red hot till they trip the high limits.

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.

Hobart LX30


Hopefully you took the suggestion to run the correct 50 amp 208-240 service to the unit.

Converting the unit to an LX30C has a couple of pitfalls. The LX30C is connected directly to the incoming water supply, which should run 120-140 degrees. By reprogramming the unit as an LX30C, the booster would be disabled, which would mean the incoming water would flow through the de-energized booster and be cooling off while it sits in there between cycles and when the unit is shut down.

The incoming fill plumbing (5/8" heater hose) would have to reconnected from the fill solenoid valve directly to the vacuum breaker on the rear of the unit to bypass the booster heater.

On the 208-240 volt LX18/30/40's, the pump motor, booster heater, and sump heater run on 208-240. To convert it to 120 volts you would have to replace the sump heater and reconfigure the motor wiring in the motor junction box.

By the time this is all done, you've downgraded a great machine, confused the next service guy, and have to deal with nasty chlorine and all of it's headaches.

Not reaching temp


On the machine that we have, there are two [2]push button switches in line for the heater tank. One is on the front of the tank and the other is around the right side. I have always called them clicks-on's but.. they are red in color and need to be rested if ever they get to hot. Be sure to relise that they did infact pop for some resone. Did the tank for some resone run dry?
