Miele Dishwasher Repair in Toronto — Not drying

• F24 is the not-drying symptom's signature on Miele: the heater-relay that switches the flow-through heater has welded contacts, taken moisture, or has plug contamination, so the heating circuit drops out and you lose the hot final rinse the brand's condensation-drying needs (Miele has no separate fan-dry on most G-series, so no heat means wet dishes). The fix is the genuine heater relay 09053390 - the EZL517A electronic unit on the water-pocket board (Elektronik Wassertasche), also catalogued 2233943 - not a full control swap. We verify the flow-through heater element and the NTC sensor read sane before fitting it, because a shorted element can take the fresh relay with it.
• F14 reads as a not-drying call far more often than owners realize: it's the heater pressure switch (B1/13) that proves circulation pressure before the controller will let the heater fire. If the wash pump can't pressurize the heater tunnel - low circulation, a blocked filter combination, a fouled switch - the heater never energizes, the final rinse stays cold, and condensation-drying produces a tub full of wet dishes with no obvious 'heat' fault. Per Miele's G-series technical literature we clean the filters and pressure switch and confirm circulation before condemning anything; it's a no-heat-because-no-pressure fault, distinct from a dead relay.
• F01/F02 are the NTC temperature-sensor (R30) faults behind a lot of intermittent not-drying: the sensor sits in the bottom of the sump and the PCB controls heating by its resistance (the spec figure Miele tests against is about 14.9k at 20C). When the sensor or its leads read open/short the controller switches the heating off or runs the program cold, so the rinse never reaches the 150-160F the condensation system needs - F02 is the open-circuit version that can test OK cold and fail as it warms. The part is the genuine Miele dishwasher sump NTC temperature sensor (e.g. 6133510), which we serial-match to the model; we ohm it cold and watch it under a heated rinse before replacing.
• The Miele-distinct not-drying cause techs miss: AutoOpen isn't working. On ECO and most current programs Miele dries by popping the door via a motorized locking rail to vent vapor, with no fan-dry to fall back on - so if the door-locking rail doesn't retract (Miele's support guidance is to contact service when the rail won't auto-retract), the steam can't escape and re-condenses onto the load. We check the AutoOpen setting is On, clear any cabinet/trim obstruction blocking the door swing, and test the rail actuator before quoting - a wet-dishes complaint that is really a stuck AutoOpen rail is the most over-diagnosed Miele drying call.
• Rinse-aid starvation is the first thing we rule out and the most common true not-drying cause on this brand: Miele's condensation drying physically depends on rinse aid to sheet water off so it can evaporate and condense on the cooler tub wall. An empty or mis-set dispenser (or a hardened/clogged dispenser flap from GTA hard water) leaves droplets clinging to glass and cutlery - the textbook 'spotted or not dry' result Miele documents. We confirm the dispenser dispenses, set the dosage up a notch for hard water, and only replace the rinse-aid dispenser unit if the flap or float has failed, not before.
• Plastics and low supply temperature are the install-side not-drying traps unique to a condensation machine: plastic items hold little heat, so they never warm enough to flash their own moisture off and stay wet even on a perfectly working unit, and Miele wants a hot-water supply around 130-140F to hit the rinse temperature drying needs. On many Toronto kitchens the dishwasher is fed off a long cold run or a tempered line, so the final rinse comes up short. We measure incoming temperature and explain top-rack plastics before anyone replaces a heater - parts don't fix physics.
• F11/F78 debris faults can present as 'not drying' second-hand: if the filter combination or circulation impeller is choked (glass, a seed, grease), circulation pressure sags, the F14 heater-pressure check can fail, and the rinse runs cold - so a drain/circulation problem shows up at the door as wet dishes. We pull the triple filter and free-spin the impeller first, because clearing debris often restores heating and drying without touching the relay 09053390 or the heater element.

Miele not drying in Toronto — the local specifics

• The recurring Toronto pattern on Miele not-drying is that most calls are not a failed heater at all - they split between an empty or hard-water-clogged rinse-aid dispenser, an AutoOpen door rail that isn't popping to vent vapor, and a short final-rinse temperature from a cold kitchen feed, with a genuine F24 heater-relay failure the minority. So we triage rinse aid, AutoOpen, and supply temperature on the first visit before quoting the factory-channel relay or NTC sensor, which keeps a lot of these from becoming a parts job.
• To these calls we carry the same-visit fixables - rinse aid, dispenser seals/flap, a bench dishwasher NTC sensor for comparison ohming, and filter-combination spares - and we confirm the model/serial on site so the drying control parts that do need ordering (heater relay 09053390 / EZL517A, flow-through heater element, AutoOpen rail actuator, the model-matched sump NTC sensor) come in correctly through the Miele factory channel on the follow-up.
