Hobart LXIH displays P2

Fill valve is stuck open

Check the spray arm. Machine water pump. After this pump pressure
builds up to the spray arm. Rubber hosejunction inside the wash tub.
This place gets connected to the spray arm system.
You can see this when you draw the tray for loading vessels.
Slowly push it and watch the junction where this gets locked into the
rubber hose mouth inside the wash tub. There should not be any
water pressure leak.

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.

The rinse thermistor is bad,on the right side in the back you will see 2 black wires connected to a white plug that screws into the piping.part number is 328994 and is about $60.Any questions i'm a hobart tech.

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.

Water is not to top sensor in alotted time.
Top sensor is in right rear corner, and is the upper of the two. Check the connector to the probe on the outside at the back. (sometimes gets wet fro vacuum breaker leaking when dirty or low flow pressure. Machine needs 20 psi flow rate

this is a probe booster error your probe failed replace it

This is a service needed indicator. It is usually shown in conjunction with another error code. Check the manual at the following link for further interpretation:
