E-2 Error on LX30 Hobart Dishwasher

Our Hobart dishwasher is displaying an E-2 error with a wrench. We've tried turning on and off the machine but it still gives us the same error. My husband swears there is a reset button but we're not sure where it's located. It's Sunday and a holiday weekend and we need the dishwasher NOW!

    We spoke to someone at Hobart and they said to make sure that we cleaned the inside because something could be tripping the sensor. My husband cleaned and scrubbed and after a couple of tries of turning it off and on, cleaning again, IT WORKED! Problem solved. We never did find out if there was a reset button but I think the turning it off and on is the reset.

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.

TURN THE BREAKER OFF AS EVEN WITH THE UNIT "OFF" THERE WILL BE 120 VOLTS PRESENT AT THE SUMP HEATER (yellow wires) DUE TO ONLY ONE LEG OF POWER BEING SWITCHED OFF!

E4 error after attempting to fill and get to temp


This is what I found for the E4 code...hope this helps...and thanks for rating my effort...The Fang.


Machine won't fill or won't fill high enough(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.
5. Delime machine.

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.

Hobart dishwasher model LX30H; displays wrench and E4.


Water is not to top sensor in alotted time.
Top sensor is in right rear corner, and is the upper of the two. Check the connector to the probe on the outside at the back. (sometimes gets wet fro vacuum breaker leaking when dirty or low flow pressure. Machine needs 20 psi flow rate

Hobart lx30 E3 error


Error Code E3 relates to a problem with the fill. Specifically that the water level has not been recognized at the middle water sensor. This can be caused by a problem with the drain system as you describe, or by low water pressure to the machine (should be 15-25psi flow), or bad wire connection to this middle sensor.
Check for proper water pressure first (should be a gauge on the machine) during the fill. Then check / repair drain as needed. These will probably eliminate the problem

Error code E2 (with a picture of a wrench)


E2 means a problem with the fill. The wrench means to contact Hobart for service
