Hobart LX30 error code wrench & E5

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

my dishwasher Hobart LX 30 will not shut off and displays 30

e5means water did notdrain below top water probe, there are 2 probes in theright corner of the mach. make sure they are clean you can use a copper tubing cleaning brush to clean probesmake sure to clean the back of them, then try 3 cycles, if after 3cyc. the e5 doesnt come back you have fixed your d/w dont forget to vote

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!

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.

E-2 error is a fill problem. Water did not reach the lower probe within the time out. (innitial fill only
1- Is the bottom probe clean?
2- No fill water (check valve, hose,fill screen in end of hose, and fill source.)
3- low water pressure, should be 20 PSI flow.
4- Fuse 1FU blown.
5- Check wiring to fill valve.
6- Check relay board function.

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.

E5 is a drain error - machine is not draining - check drain hoses - pull out machine if needed - check air gap. hope this helps. jimmy.

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
