GE Dishwasher Repair in Toronto — Leaking water

• LEAK DETECTED is GE's own flood-float lockout, and the part behind a hard leak banner is the flood switch and thermistor assembly WD21X10519 (genuine GE OEM, AP5781465 / PS8690623, supersedes WD21X10492 / WD21X20204), which sits under the fine filter in the sump on the GDF/GDT/PDT Louisville platform. A styrofoam-style float rides on water that reaches the base; once it lifts, the control parks the cycle and keeps the drain pump running to keep the floor dry. We never reset-and-run a LEAK DETECTED — we dry the base pan so the float drops, confirm whether the switch itself has stuck (debris on the float, a failed micro-switch) versus a real water path, and only fit WD21X10519 when the switch is electrically bad, not when it is correctly reporting an actual leak upstream.
• Front-of-door weeping is the classic GE door-gasket leak, and the part is the perimeter door gasket WD08X10057 (genuine GE OEM, AP3798079 / PS958908, replaces WD08X10014 / WD8X10014; an ~89-inch tub seal that also fits Hotpoint/RCA and some Kenmore). It hardens, flattens, and cracks at the door corners with age and detergent exposure, so water sheets out the front face during the wash surge. We run GE's own dollar-bill test — close the door on a bill and tug at several points around the perimeter; if it pulls free the gasket has lost its seal — then seat a fresh WD08X10057 aligned to the latch and hold it shut to take a set before re-testing under a live fill.
• Lower-corner door leaks that are NOT the main perimeter gasket are the tub corner baffles — genuine GE WD8X227 (right, AP2038859 / PS263963) and WD8X228 (left, AP2038860 / PS263964). These friction-fit rubber pieces sit in the two front-bottom corners of the tub and direct water back inward; GE's own support content confirms that when they shrink from hot water and detergent they let water escape at the bottom corners. They take no tools (friction fit) and GE recommends replacing both at once so they wear evenly. Crucially, per AppliancePartsPros most corner leaks are actually upstream — a split or cracked lower spray arm (WD22X33499) overfilling that corner — so we confirm the arm is intact before condemning a baffle.
• On the plastic-gasket trims the lower seal is a different part: the plastic lower door gasket WD08X21894 (genuine GE, supersedes WD08X10090, AP5980286), which seals the bottom edge of the door rather than the full perimeter. A unit with the light-gray perimeter gasket and the black corner baffles takes the baffle fix; a unit on the plastic lower-door-gasket design weeps from the bottom of the door when that strip warps or tears. We read which sealing design is on the cabinet off the door before ordering, because WD08X10057 and WD08X21894 are not interchangeable.
• Leaking from underneath with a dry door points at the sump-to-tub seal, not the door: on the modern Louisville GDF/GDT/PDT platform GE seals the sump to the bottom of the tub with the sump overmold and gasket service kit WD19X28199 (genuine GE OEM, AP6996843, supersedes WD19X27779), and on these and earlier designs a lock ring secures the sump to the tub. When the sump gasket perishes or the lock ring cracks, water drips between sump and tub onto the base pan and eventually lifts the WD21X10519 float as a secondary LEAK DETECTED trip. Per RepairClinic/PartSelect we lube the new gasket with a little dish soap on reseating and verify the lock ring seats fully — a base-pan leak chased to the door will keep coming back if the sump seal is the real source.
• A leak that drips even when the dishwasher is idle is the water inlet valve WD15X10003 (genuine GE OEM, 3/8" inlet) not fully closing — a slow constant weep at the valve body or its fill-hose fitting on the right side under the kickplate. Per Sears Home Services this is the tell-tale of a failed inlet valve (a drip with the machine off). The water runs down the cabinet floor, migrates into the base pan, and trips LEAK DETECTED mid-cycle even though the tub itself is sound. This is the same WD15X10003 valve implicated in GE's fill-side codes — C5 (low water fill) and C4 (water over-fill) — but on a leak call we look for a wet valve bracket and a seeping fitting rather than an underfill or overfill.
• A leak that appears only from the motor area is the drain pump WD26X22719 (the GE drain-pump kit that includes the float switch, supersedes WD26X10023 / WD26X10043 / WD26X10040, factory 165D8193G005) weeping at its impeller seal — RepairClinic's own 'Leaking From Motor Area' symptom category for GE. The seal lets water drip under the tub at the sump into the base pan, which then lifts the WD21X10519 float for a secondary LEAK DETECTED. Because GE sells this as a complete pump assembly (not a separate impeller seal), a confirmed seal weep is a full WD26X22719 swap; we verify the drip originates at the pump body, not a hose clamp above it, before condemning the assembly.

GE leaking water in Toronto — the local specifics

• The recurring GE-in-Toronto leaking pattern is a LEAK DETECTED banner that is really a door-corner or base-pan water path, not a dead flood switch — owners reset-and-run, the float re-trips, and the unit parks with the pump cycling. We routinely find the actual source is a flattened WD08X10057 perimeter gasket or shrunken WD8X227/WD8X228 corner baffles (often downstream of a hard-water-scaled lower spray arm overfilling the front corner), with sump-seal and inlet-valve weeps the next most common true leak paths. Out-of-level installs under GTA stone counters make these leak only during the fill surge, so a static check reads dry.
• We carry the full GE leak set to these calls: WD08X10057 perimeter door gasket, WD8X227/WD8X228 corner baffles (as a pair), WD08X21894 plastic lower-door gasket for the plastic-seal trims, WD15X10003 inlet valve, WD21X10519 flood-switch-and-thermistor assembly, and the WD26X22719 drain-pump kit — plus the WD19X28199 sump overmold-and-gasket kit so a base-pan-leak diagnosis doesn't become a second trip. We dry the pan to drop the float and pressure-test under a live fill before fitting any part.
