LG Washing Machine Repair in Toronto — Leaking water

• The signature LG front-load leak is a torn door boot/gasket. On the WM3360/WM3550 lineage (and the Kenmore Elite 796 LG built) the boot is the genuine MDS47123604 (AP5332003; supersedes 2003274/MDS47123606/PS3628576), confirmed to fit WM3360HRCA/HVCA/HWCA and WM3550HVCA/HWCA. It splits or perforates at the 6 o'clock fold where coins, hairpins and grit collect against the rubber, so water drips to the floor on the wash fill. LG's leak help library lists the door gasket among the leak sources and tells you to inspect it for tears and clear hair/lint/residue; in our field experience overloading also traps laundry against the gasket and accelerates the tear. We replace the boot rather than patch it, re-seat both the inner and outer spring clamps with the clamp tang at the correct index, and pull any item caught at the fold before quoting.
• Inlet-valve leak with overfill is the LG fill-side leak, and the code that fits this leak is FE (fill error / overfill): water keeps entering after it should stop. The triple-solenoid cold inlet valve 5221ER1003A (also sold as 5220FR2075L; AP5986564 / PS11728995, supersedes 5221ER1003C / 5221ER1003D / 5221ER1003F) cracks at the plastic body or fails to seat closed, so the tub overfills and water escapes or the machine fills while it sits idle. LG's documented FE cause is an inlet valve that won't shut off the flow; hard-water scale on the solenoid seat is the usual reason a valve holds cracked-open. Note the IE (inlet error) code is the opposite complaint - a no-fill / slow-fill supply problem (closed tap, low pressure, blocked inlet screen), not an overfill or a leak - so IE points to an under-fill diagnosis rather than this leak. We confirm a passing valve (water entering with the cycle off) before condemning it, and check the rear inlet hose washers and screen, since a weeping coupling at the back-left mimics a valve leak.
• Drain-pump-area leak (not the door): the drain pump & motor assembly 4681EA2001T (AP5328388 / PS3579318, supersedes 4681EA1007G / 4681EA1007D / 4681EA2001D / 4681EA2001N) weeps from a cracked volute housing or from around the motor shaft during the drain step, dripping into the base pan at the lower-front. This is the same pump behind the OE (outlet / no-drain) code on our sheet, so a wet pump body with intact drainage is a leak call, not a no-drain call. We confirm the leak is the housing and not the rubber sump hose or its spring clamps first; if the pump body itself is cracked or seeping at the shaft it is replaced as a unit, since the impeller and seal are not sold separately on this platform.
• Sump-hose / tub-to-pump bellows leak that only shows on certain steps: the large rubber sump hose between the outer tub and the drain pump, and its spring clamps, split or pop loose and drip at the lower-left front of the chassis. A split here is often dry at rest and wet only when the tub is full or pressurized on drain, which is why owners report an intermittent puddle. We trace and pressurize the tub-to-pump path, re-seat both spring clamps, and check the boot drain port and the dispenser-housing hose connections rather than re-stretching a tired hose, because a cut-and-reuse hose ruptures again within weeks.
• Detergent-dispenser drawer overflow leak: LG's own dispenser help page documents three causes - pulling the drawer out past its stop, water hotter than 50C/122F causing excessive foaming overflow, and simply using too much detergent. Separately, the common field cause we see is clogged siphon caps/tubes in the drawer (typically liquid fabric-softener and detergent buildup) plus a partially blocked hose from the dispenser housing to the drum; when the siphon can't clear, fill-water backs up and runs out the front. This siphon-cap cleaning is general HE-washer maintenance, not an LG-documented cure: we pull the caps and inserts and scrub every channel until daylight shows through, dose HE detergent correctly, and only replace the dispenser assembly if a cap or housing port is physically broken. We show owners the drawer and siphons rather than selling a part on what is really an overflow.
• Outer-tub-seal leak from underneath on older WM front-loads, which is a consequence fault and the only teardown path: the tub seal hardens or scores and water weeps down the centre shaft and pools under the machine, and left alone it corrodes the bearing into a jet-engine spin roar. The repair is the LG ER-WB4036 tub bearing/seal kit, which bundles the tub seal 4036ER2004A and seal gasket 4036ER4001B with the large and small tub bearings 4280FR4048L and 4280FR4048E. We confirm the leak source is the shaft seal and not the boot, valve, pump or sump hose first, then have the tub-and-bearing economics conversation up front, because on a high-mileage WM a full bearing teardown rarely pays against the cheaper boot/valve/pump leaks above.

LG leaking water in Toronto — the local specifics

• The recurring LG-in-Toronto leak pattern we see is a torn MDS47123604 door boot on a heavily-used front-load - often with a coin or bra wire still sitting in the 6 o'clock fold from an overloaded wash - and, on hard-water households, a steady run of FE/overfill leaks where the 5221ER1003A inlet valve won't seat closed and dispenser-drawer overflows from clogged siphon tubes. Older WM boxes show up with the under-the-machine tub-seal weep that has already started into a spin roar.
• We carry to these LG leak calls the MDS47123604 door boot, the 4681EA2001T drain pump and the 5221ER1003A / 5220FR2075L cold inlet valve, plus fresh sump-hose spring clamps and inlet-hose washers; the ER-WB4036 tub bearing/seal kit (4036ER2004A + 4036ER4001B + 4280FR4048L/E) is brought only after we confirm a shaft-seal leak against the model and serial.
