Dishwasher

View all 9 codes →
CodeMeaning
E01The E01 code means the main power control module detected an internal fault in the high-voltage power stage that controls the heater and motor drive circuits. The processor ran its self-check and found something it can't work around on its own.
high
E09The control board ran a heating check and the water temperature didn't rise the way it's supposed to during the wash or dry phase. Either the element can't generate heat anymore, or the NTC sensor is feeding the board bad temperature data and it thinks something's wrong even when it might not be.
moderate
E15Water leaked into the base pan sitting below the dishwasher tub. A polystyrene float in that pan rose with the water level, pushing against a microswitch that triggered the AquaStop lockout. The machine won't run again until that float drops back down and the pan is dry.
critical
E22The dishwasher's sensors detected restricted water flow through the triple filter assembly. Water can't recirculate to the spray arms properly, so the machine throws E22 and stops rather than run the pump dry or just leave you with filthy dishes.
low
E24The control board ran the drain pump for the maximum allowed time and still detected water sitting in the sump. Could be a blockage stopping flow, or an actual pump failure. The board gives up and throws E24 rather than running the pump indefinitely.
moderate
E25The drain pump's impeller is physically blocked. Something slipped through the filter system, landed in the pump housing, and locked the spinning blades up. The machine detects that the pump motor is straining or stalled during the drain phase and throws E25 to stop the cycle.
moderate
HUBYour Thermador's control board detected a sensor reading outside normal parameters. Whether that's a blocked drain, water in the base pan, a heating failure, or a low supply level, the machine locked itself out to protect the motor and your floor. It's not broken, it's telling you something specific.
low
RESETWhen the control board detects a fault or gets confused mid-cycle, it locks up and stops accepting new commands. A reset wipes that locked state from memory and lets the board reboot fresh. Think of it like force-restarting a frozen phone. Basically the same idea.
low
SA-NLThe machine's sensors have detected that both the water softener salt reservoir (in the tub floor) and the rinse aid dispenser (on the inner door) have dropped below their minimum fill thresholds. Both need to be topped up before the indicators clear.
low

Oven

View all 6 codes →
CodeMeaning
F24The RTD probe, which is what Thermador uses instead of a basic thermistor, is either reading outside its normal resistance range or has gone open circuit entirely. The control board gets no usable temperature signal and locks the oven out so it can't run unsafely.
moderate
F34The board detected a relay that won't open or close the way it's supposed to. Those relays are heavy-duty switches that control power to your bake and broil elements. When one sticks closed or burns open, the board flags it and shuts down to protect you.
high
F64The primary control board has detected a definitive internal fault and cannot continue operating. F64 is more specific than F7 and less likely to be a transient fault.
high
F7Basically the control board hit a fault condition it couldn't recover from on its own. Could be a door switch not confirming the door's closed, could be an internal relay hiccup on the board itself. Sometimes it's just electrical noise from a power surge. The board flags F7 and locks things down until you clear it.
high
HUBThe oven's control board monitors the RTD temperature probe constantly. When it detects resistance outside the expected range, or loses communication with the probe entirely, it throws an F-code and shuts down heating to prevent a runaway temperature situation. Different codes point to different parts of that communication chain.
low
PROBEThe oven's RTD temperature probe is disconnected or has failed. PROBE displays on newer Thermador models with full LCD panels; older models show F24 for the same condition.
moderate

Refrigerator

CodeMeaning
NOT-COOLINGThe fridge compartment or freezer has climbed above its target temperature and stayed there. Something's stopping the system from pulling heat out, whether that's blocked airflow, a frozen evaporator, a dead fan, or the compressor itself giving up.
high
