    In that drawer there may also be another circuit breaker to the back right,also depending on what year of your model there may be a fuse and transformer that sit behind the unit to the left near the motor.If you can use a meter i can walk you thru some voltage tests.

I have a Hobart Dishwasher model LX30, it seems to stall when in the fill cycle from the start, which blocks any further function except shutting down, on the screen there appears a wrench insignia.

Hobart LX30H ML 104354 Manual Page 28
According to the manual ... the wrench icon comes on with OTHER codes for the LX30. Did you get a flashing P1, P2 or P3?
Or for that matter, get any associated E codes to come up?

Depending on the P or E codes there are fixes discussed on prior Fixya answers for this machine ... search there for more help

Have a hobart lx3011 and just quit working. where and how many fuses in it?

Not sure if you have an LXIC or an LX30.
Both have a pull out drawer at the top. Both have the main connection of power on the contactor in the front left corner. Both have control circuit fuses between the contactor and relay board.
Use caution with a digital meter to test.

P1 error code on LX30 Hobart

This is a bad sump temperature probe. The unit will function, but will not heat nor display the wash water temperature.

This is a very easy fix. Order Hobart part number 328994 from your nearest Hobart parts dept.

Turn off and drain the unit. Kill the power to the unit at the circuit breaker. Remove the lower front cover. Locate the screw-in temperature probe at the front of the sump. Unplug the sensor from the wiring harness, remove with a 7/16" open end wrench. Screw in the new probe, using teflon tape of the threads, snuggly. It does not need to be super tight. Plug it into the harness, reinstall the front cover, turn the breaker back on, and start up the unit.

Programming LX18H for TRUE FILL AND DRAIN

The LX18 series was a compromise machine, the lack of a sump heater causes numerous rinse temperature problems due to it's increased water use (over the sump-heater equipped, fresh water rinse LX30 series).

The LX18H can be reprogrammed for true fill and dump operation. If you still need to do this, please let me know via e-mail or post a reply, otherwise a won't post the long answer!

(I worked for Hobart as a service tech. from 1994 until 1999, and have been independent since then)

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.

Dishmachine won't fill

Your problem is as straightforward as your observation, the unit is not getting enough water flow.

First, if your DW water is hooked up with a braided stainless hose, there is usually a screen in the end of it, (check both ends). It gets clogged with debris and chokes off the water. Make sure the line is not kinked.

If that doesn't work, you are likely having trouble with your fill valve. It is under the front kick panel. It has a large castle like upper cap. It is common for debris in the water to make this valve malfunction. It isn't too difficult to open up without removing. Just watch how it is assembled. If you pay attention, it's easy. If you have a booster, the hoses are very brittle with age.

And otherwise, the fill valve may be bad. REMEMBER, verify your supply water flow where it connects to the machine first. Don't assume. You could have a pressure regulator or a line strainer that is part of your supply line. They do fail. But that's a plumber's fix, not a technician.

Hobart lx30 : rinse cycle

The rinse water in a LX30 is driven by water pressure. A solenoid valve, bottom front - gold body, opens up and allows the water to flow.

If you are referring to the rinse agent pump, there must be NO leaks in the tubing or the hose that runs through the pump. And if the unit has lost its prime, using your hand to "seal" it, and forcing water from the faucet into the line can prime it.

Good luck - Mike
