9 error 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.

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.

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.
criticalintermediate
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.

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.
moderatebeginner
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.

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.

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.
lowbeginner
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.
