GE dishwasher model GDF670SYVFS won’t start and the buttons don’t respond—what could be wrong?
Appliance ExpertHi, I’m Mike, your appliance troubleshooting expert—when you press the buttons, do any lights come on or beeps sound, and is the Control Lock indicator lit?
No lights or beeps at all, panel’s just dead; Control Lock isn’t on.
Appliance ExpertDid this begin after any power cut or a breaker/RCD trip?
No, power’s been steady; it ran last night and today it’s just not working at all.
Appliance ExpertBefore it went fully dead, did the touch buttons ever act intermittent or need extra pressure?
Yeah, kind of—some buttons were flaky last week, had to press harder.
Appliance ExpertAbout how old is the unit, and is it plugged into a standard socket or hardwired?
Around 2 years old, plugged into a normal socket behind it; socket seems fine.
Appliance ExpertThanks, that helps; based on a totally blank panel, no beeps, and earlier flaky keys, the most likely culprits are: 1) a failed or water-damaged user interface control panel (the touchpad/board), 2) a loose/burned power connection at the dishwasher’s junction/cord connection, 3) a failed line filter/power module, or 4) less commonly, the main control board, while a door latch switch issue is unlikely because the UI usually still lights with a bad latch. For safety, mains power inside the base can cause electric shock—avoid opening panels unless the unit is unplugged; if you’ve noticed any burning smell or heat at the plug area, stop using it and have it inspected. Given your symptoms and the prior intermittency, the user interface board and its ribbon/harness are the top suspects, with the power connection next; a technician would verify incoming voltage at the plug, inspect the power connection block for heat damage, and then test the UI-to-main board communication before condemning the main board. Typical repairs: UI panel/board replacement is common on this series; power-connection or line-filter issues are also straightforward; costs vary by region, but expect roughly €120–€250 for parts plus labour. Since it’s about 2 years old, check your purchase date—EU consumer guarantees can be up to 2 years via the retailer.
