Before you book,
in this order.
Each step comes from GE's own guidance for C7 on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Switch the breaker off for about half a minute and back on, then reset the dishwasher.
Run a short cycle and watch whether C7 returns.
If it does, book a visit — the sensor and its wiring need to be measured.
What not to do
Do not confuse C7 with C6. C6 is about cool water from the house; C7 says the part that measures temperature is not reporting.
