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

SOURCE: 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!

Testimonial: "You were right! can you help mr with a P2 error code?"
This unit is a dinosaur. The 3-phase converter had to cost twice as much as the unit. Best solution - turn the power off to the 3 phase converter when not in use.
Better best solution - find a newer unit that will be repairable should it need service. Virtually nothing is available for the AM9 series of dishwashers.
Suggestion - talk to a commercial dishwasher chemical provider that leases dishwashers. They may have a surplus unit that they picked up from a customer (that they leased a new machine to) that they may be willing to donate.
