LX30H THROWS A CODE EO after running awhile. I hit the high reset button under the flaps on the front for both the boost and reg elements . It will work for a couple cycles and then does the same thing....


Machine won't fill or won't fill high enough. site water pressure meets minimum flow pressures. (LX18, LX30 display shows working.
"E0," "E2," "E3," or "E4". LX40 display shows "DR1 PRBLM," "FILL1 PRBLM," FILL2 PRBLM," or "FILL3 PRBLM". Machine will not run.)

1. Low water pressure - check for clogged hose strainer; check that

2. Make sure probes are clean

3. No water pressure - main water supply valves may not be

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.

I have a PD code on a Hobart LXI dishwasher. What does that mean


PD is not an error code. It shows that when it draining water out shortly after power-up and when shutting down. If it seems to be showing "PD" longer than usual, it means the dishwasher's control circuitry believes there is still water in the tank, due to a faulty water level probe, most like the one under the lift-out screen. It has a plastic body with a metal probe coming out the center.

There is also a dual probe at the rear of the machine, but I believe the dishwasher uses the front probe to determine when to stop draining the machine during "PD" - most likely meaning "Power Drain" or "Power Draining".

If you are not seeing any E- codes (E1, E2, E3, etc.) then these water level probes are likely just fine and the "PD" is appearing normally, as it should during draining conditions.

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!

E5 everytime we run the wash


Try running the drain hose into a bucket next to the machine. If it drains Ok, look for the restriction in your plumbing. If it won't drain into the bucket, look for a closed drain valve, open fill valve, bad middle or top probe, check power at drain connector ( it's DC volts from the bridge rectifier in the top drawer on the relay board.. Basically, water is at top probe at beginning of rinse, or it didn't drain down after the wash. Drain hoses can kink from hot water if not routed well.

LXGH E5 Code


I need to check my codes to be positive. And I'll check them this weekend. But, I believe E5 is from excess water in the unit, and so it won't go into rinse and add more water.

First and most common -- the drain hose, at the back of the unit is kinked. The unit gets pushed back against the wall and kinks the line.

Second, your probes are dirty. The ones in the back right corner detect water level. Clean them with a green scrungee even if they look clean.

Good luck - Mike
