Maytag Dishwasher Repair in Toronto — Not drying

• The classic no-heat not-drying fault is an open heating element: it isn't heating, so the final hot rinse never reaches temperature and the dishes finish wet. Because the modern stainless tub dries by condensation on the cooler tub wall after a hot rinse, no heat means no dry. On no-display Maytag MDB models this shows up as the Clean light blinking 7 times, which the diagnostic charts attribute to a heating-element or thermistor fault (note this 7-blink flash pattern is NOT the same as the alphanumeric F7E1 code, which on this dishwasher platform is a wash-motor/circulation-pump fault, not a heater fault). We don't assume the element from the blink alone: we ohm it for continuity first (a healthy element reads roughly 40 ohms at room temperature; open or burnt = replace). The cure on a confirmed open element is the genuine heating element W10518394 (fits MDB6769PAW1, MDB4630AWS2 and the MDB family; supersedes 8194250 / W10134009 / W10441445), and we ALWAYS serial-check any 2006-2010 plastic-tub unit against the June 3, 2010 CPSC heating-element recall before touching the heat circuit.
• A wet load with a heating element that tests good is the thermistor/OWI story, not an element job. The soil-sensor/thermistor assembly (optical water indicator, genuine WPW10705575 / W10705575) tells the controller the wash temperature; if the sensor reads cold-biased it satisfies the heat logic early, the rinse never reaches drying temperature, and the dishes come out damp with no obvious element fault. We watch the thermistor under a heated rinse and clean the scaled OWI lens with white vinegar before fitting WPW10705575 - a scaled lens is a no-part fix.
• On the fan-assisted variants - the WDT-prefix Whirlpool sister-badge units, KitchenAid sisters, and Maytag's newer 'Heated Dry with Fan' hybrid-tub models - drying leans on a vent-and-fan that opens at the end of cycle to push the humid air out. A seized fan motor or a wax-motor vent flap that won't open traps steam that re-condenses on the load. The genuine vent and fan assembly is WPW10469574 (supersedes W10375833 / W10462768 / W10195024 / W10195034 / W10469574). We free-spin the fan blade by hand and continuity-test the motor, and confirm the flap actuates, before quoting the assembly. The standard MDB stainless tall-tub has no such fan - it is condensation-only - so we identify the platform first.
• Rinse-aid starvation is the most common true not-drying cause on this platform and the first thing we rule out. Condensation drying physically depends on rinse aid to sheet water off glass and stainless so it evaporates and re-condenses on the tub wall instead of beading on the load. Maytag's own guidance sets the dispenser at 2-3 from the factory and tells hard-water households to raise it toward the maximum; an empty dispenser, a clogged dispenser flap (GTA scale hardens it), or heated-dry simply deselected on the cycle all leave a wet load with no fault code. We confirm the dispenser actually dispenses, dial the dose up for Toronto water, and verify Heat/ProDry is selected before condemning any part.
• Plastics and a low incoming-water temperature are the install-side not-drying traps unique to a condensation machine. Lightweight plastic items on the top rack hold almost no heat, so they never warm enough to flash their own moisture off and stay wet even on a perfectly healthy unit. And the tub can only dry as hot as the water it's fed - a dishwasher teed off a long cold run or a tempered line in a Toronto kitchen brings the final rinse up short of drying temperature. We measure the supply temperature at the tap and explain top-rack plastics before anyone replaces a heater, because parts don't fix physics.
• A blocked spray system or fouled filter shows up at the door as wet dishes second-hand: if the coarse/fine filter is choked or the diverter feeds only one rack, the load never gets a complete hot rinse, so half of it finishes cold and wet even with a good element. We pull the filter (quarter-turn counter-clockwise), flush the sump, and clear scale-plugged arm jets, then confirm a full hot rinse before we look at the heat circuit - clearing debris often restores drying without touching the W10518394 element or the WPW10705575 sensor.

Maytag not drying in Toronto — the local specifics

• The recurring Toronto pattern on Maytag not-drying is that the call is split roughly in two before any part comes out of the van: genuine open-element / cold-biased-thermistor heat faults on one side, and rinse-aid/hard-water/heated-dry-deselected no-fault drying complaints on the other. Owners routinely read normal condensation on the tub wall, or wet top-rack plastics, as a broken machine. We read the Clean-light blink pattern, ohm the element for continuity, and check the dispenser and supply temperature on arrival so the visit ends in either a confirmed element/sensor swap or an honest water-chemistry demonstration, not a guessed part.
• We carry to every Maytag not-drying call: the W10518394 heating element, the WPW10705575 OWI/soil-sensor-thermistor assembly, a rinse-aid dispenser, and - when the platform decode says it's a WDT-style fan-assisted or hybrid-tub unit - the WPW10469574 vent-and-fan assembly. We also bring a thermometer for the incoming supply, vinegar for a scaled OWI lens or dispenser flap, and affresh for a hard-water demo, because a large share of these calls clear without a part.
