Fault area and what the code does not prove
Separate the manufacturer-defined condition from components that still need exact-model diagnosis.
Safe next steps
- 1Confirm the exact GE Appliances Dishwasher C7 model and displayed code before taking action.
- 2Keep the appliance in a safe state and use only the external checks named in the official source.

- 2Confirm that the full model number is covered by this scope: GE Appliances dishwasher models covered by the official Dishwasher fault-code article; not every code appears on every model
- 3Confirm that the observed condition matches the published meaning: the water-temperature sensor circuit is inoperative
- 4Confirm that the full model number is covered by this scope: GE Appliances dishwasher models covered by the official Dishwasher fault-code article
- 5not every code appears on every model
- 6Published check — Disconnect power at the breaker for about 30 seconds, reset once, and contact service if C7 returns
- 7Published check — do not open the sensor circuit
- 8Stop at the published service boundary after these actions
- 9do not add a restart or test cycle that GE Appliances does not specify for C7
- 10Published check — Give service the C7 photo, full model and serial number, when it appeared, and the result of every published external check
Service-safe actions
- 1Disconnect power at the breaker for about 30 seconds, reset once, and contact service if C7 returns
- 2do not open the sensor circuit
- 3Give service the C7 photo, full model and serial number, when it appeared, and the result of every published external check
Repair planning
C7 cost planning: €0 for the published breaker, plug, or power-restoration check. If the household supply or appliance wiring needs diagnosis, €90–€220 is a typical Europe planning range for diagnosis before parts; it is not GE Appliances pricing.
C7 time plan: The official action includes about 30 seconds. 5–15 minutes to document C7 and complete the published power check; allow 30–90 minutes for a qualified supply or appliance diagnosis.

C7 parts decision: C7 documents the water-temperature sensor circuit is inoperative. It does not by itself distinguish the appliance, cord, outlet, breaker, or installation wiring as the failed item; a qualified electrical check must locate the fault before parts are ordered.
What not to do
- Do not use an extension lead, bypass a tripping breaker, open a plug or control enclosure, or measure live mains voltage
- Stop immediately if C7 follows heat, arcing, smoke, or a burning smell
- Do not run an extra test cycle after the source tells you to stop or arrange service for C7
Preventive maintenance
- 1Follow the exact GE Appliances maintenance schedule for the dishwasher and keep the model, serial number, and service history available
- 2If C7 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
