It seems that the rinse probe thermistor open or shorted.

P3 code refers to the probe near the airgap at the back. It is monitoring the rinse temp. P2 is the booser probe, and P1 is the wash tank. The control board will store error codes, so once changed, you can access the memory and clear it.

P2 error is the final rinse probe. Depends on the model of the D/W for location, next to the vac breaker.

p2 would mean your rinse thermistor is open or shorted. its located on top near the the right side, after the vac. brkr. part# is 328994. remove old, istall new . dont forget to vote,hope this helps , monomoy

the p2 err. is on open or shorted rinse thermistor which is located on the back of the mach next to the vac. brkr. as for draining ck the drain valve for debris, and the end of the drain hose where it connects to the building drain

The p2 code is your rinse thermistor is bad,if you gain access in the back on the top right side you will see a probe with 2 wires going into the rinse piping.Use a 7/16 wrench and unscrew.Very easy to replace.When the machine goes into the rinse cycle the temp display goes up/down?The part is about $60.Part # 328994.I'm a hobart tech any ? let me know and please rate me.

Does it show a wrench icon and P1?
error codes are p 1to 3 for probe errors, or E1 to 7 for error codes.
P1 is the probe on the wash tank. It's a thermistor with two black wires to a white connector. There is another on the booster front (P2) and a 3rd on the rear airgap, (p3). You could try exchanging 1 and 3 to see if the fault changes too. You have to drain the booster to swap P2. If it can't determine the wash tank temp, it won't know to control the heat and shows the error.

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.
