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.

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)

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

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.

If this doesn't help let me know and I will get to the bottom of it....good luck and thanks for rating my effort...The Fang.

I just searched and find no information on Hobart machines

this all I can find Machine will not fill or will not fill high enough. (Display shows E0, E2, E3 or E4. Machine will not run). 1. Low water pressure - check for clogged hose strainer; ensure the site water pressure meets minimum flow pressures. 2. Make sure probes are clean. (See Cleaning.) 3. No water pressure - main water supply valves may not be working. 4. Anti-siphon valve - located in the lower left area of the chamber just above the water line. Drain the machine and insert toothpick or similar object into hole to verify ball (3?16" OD) is free to float. 5. Delime machine perhaps the wax is plugging up the floating ball area

A hobart LXIH-3 uses a chemical to sanitize however a 120 degree wash temp is required as well.

Turn up your hot water tank that supplies the dishmachine, make sure your sanitizer is pumping into the rinse cycle using micro-clorine test papers and all is well.

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!

The fill solenoid is behind the lower panel, attached to the left side of the booster tank. There is a screen in the end of the fill hose that may be clogged. You require 20 psi flow rate to run the machine properly.
Pull the top tray out, place a magnet on the door switch, with the door closed and monitor the 3 led lights on the control board while its filling. All 3 should light up. Use caution around the high voltages present on the relay board and the booster contactor.
The probes in the right rear corner of the tank send the water level signals to the control board. The tips must be clean of scale or debris that may signal that water is present, when it is not.

Your detergent is to strong .if the dishwasher is used mainly for glasses use a detergent that is for glassware

could be the drain valve has lost its internal seal . The machine may be accepting a charge of water during the fill cycle, and loosing it while the pump is running

Hobart 24 in.... | Answered on Mar 23, 2014 | 99 views


mark the chemical bottle and observe over time. Chances are the silicone tube inside the pump has collapsed and needs changing.
Caution... use protective gloves and face protection because the chemicals will spill out and could splash. The detregent is very corrosive. Read the MSDS sheets.
