Hobart Commercial Dishwasher Error Codes P1, P2, P3: Wrench Lit
On a Hobart AM15 dishwasher, a lit wrench with P1, P2 or P3 on the display has no meaning given in the manual. The manual says to contact your local Hobart Service Office.

What does Hobart error code P1 / P2 / P3 mean?
Some AM Select machines show a wrench symbol that lights up, together with P1, P2 or P3 on the display. The manual's troubleshooting table lists these without any explanation of what each means. Its only instruction is to contact your local Hobart Service Office. As with E6, that means the operator cannot sort the cause out with the visible parts of the machine. A lit wrench in general suggests a service-type message, but the manual does not say that, and this page makes no claim about what the P numbers stand for. What can be done is to record which of P1, P2 or P3 appears, whether the machine still washes, and what the machine was doing at the time. Those notes let the technician arrive with the right information, and they avoid the operator trying standpipe, strainer or water supply checks that the manual does not link to these displays.
