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.

that is called the wash pipe the part# for the pipe is 893457. that can be bought @any hobart office in your area

Frank,does the sump probe (the one underneath the screen) look good?It should have at least one quarter inch of metal.I have seen these break and its hard to tell but the info your describing sounds like that probe is bad or the control board.I'm a hobart tech and can help you troubleshoot,let me know----Tony

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.

This is what I found in the manual...and on a couple of other sites....

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.

this is asensor error unit not filling fast enough or loose connection

$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.
