Dishwasher is completely unresponsive — no lights, no sounds, no cycle initiation. A blown thermal fuse cuts all power to the unit.
Display and buttons are completely dark and unresponsive. The thermal fuse is the first component to check when the panel won't illuminate.
Appliance stops unexpectedly during wash or rinse cycle and cannot be restarted. Indicates the fuse tripped due to an overheating event.
Dishwasher runs unreliably — starts sometimes but not others. A partially degraded thermal fuse can cause erratic electrical continuity.
Control board displays an error code related to thermal protection. Replacing the fuse clears the fault and restores normal operation.
💡 Pro Tip: How to Know Your Thermal Fuse Has Blown
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher completely dead — no lights, no response when pressing buttons
⚠️ Control panel does not illuminate but the door beeps when closed
⚠️ Dishwasher cuts out mid-cycle without warning and won't restart
⚠️ Error codes on display indicating a thermal or overheat fault
🔍 Diagnostic tip: Use a multimeter set to continuity mode and probe both terminals of the fuse. A good fuse will beep (closed circuit). No continuity = blown fuse — replace immediately. Always also check the door latch (W10619006) and control board (WPW10380685) before ordering, as all three can cause a no-power symptom.
