E3 is showing up on the screen. We were told in the past this means that the probe is clogged we cleaned it out the way the guy showed us but this has not solved the problem.

E3 is -- water did not reach the middle probe in time. It's the longer of the two probes in the right rear corner. they should be white plastic insulators with stainless pins . Scale may be built up on the pins. Check for corrosion on the probe assembly connector on the rear outside. The connector is directly under the vacuum breaker which will leak if dirty of if pressure is low.. Watch the control board leds to monitor water level as it's filling. make sure you have 20 PSI fill flow pressure. Your system may be choked with scale restricting flow rate.

I use this dishwasher in a florist to clean wax out of candle glass and recently it is not working. E4 codes appear, and it over flows sometimes.


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

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.

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.
