Washer Not Draining in Sudbury
Wash cycle finishes and you open the lid to a tub full of cold, soapy water. Or the spin cycle never starts because the machine cannot get under its low-water threshold. Washer not draining in Sudbury is one of our top-five service calls, and roughly half resolve in the laundry room before we ever load a parts truck. The other half are pump or pressure-switch failures that need a technician with the right part on the van. These 6 checks tell you which side you are on.
First, classify what kind of not-draining you have
Three patterns of standing water tell three different stories.
Full tub at cycle end usually means the drain pump never ran. Suspect: blocked impeller, wrong pressure-switch reading, lid switch never closed, or control board cut out before drain.
Half-full tub with brief spin usually means partial blockage. Pump runs, flow is restricted. Suspect: kinked hose, sediment buildup, partial impeller jam, or a standpipe clog.
Error code on the panel (most often E1, E2, F02, F21, LE, or LF on Whirlpool, Maytag, LG, and Samsung machines) means the drain failed twice and the machine quit. Same checks apply. Front-loaders are about 4x more likely to show codes than top-loaders.
Note which pattern fits before you start. Checks 1 to 3 are the cheap fixes. Checks 4 to 6 need parts and labour.
Check 1: The kinked drain hose + standpipe test (5 minutes, free)
Pull the washer 6 inches out from the wall. Look at the corrugated drain hose where it exits the back of the machine and arches up into the standpipe.
What you are looking for:
- A sharp kink behind the washer (the most common cause in Sudbury basement laundry rooms with tight clearances)
- Hose pushed too deep into the standpipe (siphons back during fill)
- Hose end too shallow, under 36 inches off the floor, so the pump cannot push uphill
- Standpipe rim caked with grey lint-soap-sediment paste (Sudbury hard-water classic)
The fix: straighten the hose into a smooth arc, set the standpipe entry between 36 and 96 inches above the floor, and run a fresh empty drain cycle. If water flows freely, you are done.
Cost reality: $0 if you do it yourself. About $90 to $140 if a technician makes the trip just for a hose re-route.
Check 2: Clean the coin trap or pump filter (front-loader essential)
Front-loaders (most LG, Samsung, Whirlpool Duet, Maytag MHW series) have a small access door on the lower front. Open it, place a shallow pan beneath, and slowly unscrew the filter cap. Expect 2 to 4 cups of dirty water first attempt. Expect coins, bobby pins, a sock or two, and a grey lint-soap clump the size of a tennis ball.
High-efficiency top-loaders (Whirlpool Cabrio, Samsung WA) often hide a similar filter under a snap-off panel below the dispenser. Older top-loaders do not have one.
Worth saying on the phone: if you have never opened this filter and the washer is more than 18 months old, this single step has roughly a 35% chance of resolving the call before we roll a truck. Clean it every 3 months on hard-water Sudbury feeds, every 6 months elsewhere.
Cost reality: $0 if you do it yourself. Some Donovan and Flour Mill homes on softener-bypass lines build up enough scale that the filter housing itself corrodes ($40 to $80 housing replacement).
Check 3: Foreign objects in the pump impeller
If the filter came out clean but the pump still will not move water, something is jammed in the impeller itself.
Symptoms: pump motor hums or buzzes for 5 to 10 seconds at drain start, then quits. Maybe a faint thunk when it tries to spin up. Maybe the pressure switch resets and retries 30 seconds later.
The check (front-loaders): with the filter cap off, shine a flashlight into the housing and look for the impeller blades. Try to rotate them gently with a chopstick or screwdriver shaft. Anything that prevents free rotation is the culprit. Most common finds: a bra underwire (about 40% of stuck-impeller cases), a sock corner, a baby sock entirely, a wood chip from carharts tossed straight into the wash, a sliver of broken plastic from a hair clip.
Cost reality: $0 for homeowner removal. About $90 to $140 if the impeller has to come out of the housing to clear it. Do not run the washer once you hear the hum-and-quit pattern. You will fry the pump motor in three or four attempts.
Check 4: Listen for the drain pump (diagnosis without tools)
With the lid closed and the cycle on drain, press your ear to the front-left or back-left of the washer (where the pump usually lives).
- Silence: pump is not getting voltage. Lid switch, door lock, board, or wiring fault. Move to Check 5.
- Hum then quit: impeller blocked (see Check 3) or motor windings seized. A seized motor needs a new pump.
- Smooth whir, no water moves: impeller broken (snapped vanes). Usually the next-cheapest failure after a clog.
- Rattling or grinding: bearings gone. Pump is on borrowed time.
A 5-year-old pump humming-and-quitting will usually respond to clog removal and last another 1 to 3 years. A 10+ year-old pump showing any of those four sounds is end-of-life.
Cost reality: drain pump replacement runs $140 to $280 in Sudbury, including the part and 60 to 90 minutes of labour. Whirlpool, Maytag, and Kenmore pumps sit on the lower end. LG and Samsung sealed-pump assemblies push to the upper end.
If you cannot confirm which sound pattern fits and want a sane second opinion before paying for a new pump, send us the brand, model, and sound and we will tell you whether the machine is worth fixing or worth replacing.
Check 5: Lid switch (top-loader) or door lock (front-loader)
If Check 4 showed silence, the board never sent the drain signal. Almost always because the safety switch never confirmed the door is closed.
Top-loader lid switch test: close the lid, lift it 2 to 3 inches, then close it firmly. You should hear a soft click as the magnet engages and the small reed switch closes the circuit. No click means the switch is broken or the magnet is missing (often pulled out by toddlers).
Front-loader door lock test: close the door, start a drain cycle, listen for the lock solenoid to engage (a sharp clack within 2 seconds of cycle start). No clack means the lock failed open and the board will refuse to drain.
Cost reality: lid switch is $40 to $90 plus 15 to 30 minutes of labour. Front-loader door lock is $80 to $180 plus 30 to 60 minutes. Common in Hanmer and Val Caron rental homes where the lid has been slammed thousands of times. The magnet snaps out of the housing first.
Check 6: Pressure switch + control board reset (the brownout-recovery check)
If Checks 1 to 5 came back clean and the washer still will not drain, the failure is in the electronics. Two suspects, in order of likelihood.
Pressure switch. A small disc-shaped sensor connected to the tub by a clear hose. It tells the board how full the tub is. If the hose has lint or sediment blocking it (very common on hard-water Sudbury feeds), the board thinks the tub is full and refuses to start the drain pump until the level drops. The fix: disconnect the hose, blow it clear, reconnect. About a 20-minute job, $0 in parts if the switch itself is fine.
Control board after a brownout. Hydro One restoration cycles on Highway 17 East and Highway 144 routinely brown out the panel for 5 to 30 seconds. Many washer boards lock into an error state and refuse to acknowledge the drain command. The fix: unplug for 60 full seconds (not 10), then plug back in and re-run an empty drain cycle. Resolves about a quarter of post-storm calls. If the cycle still refuses, the board itself may need replacement ($220 to $480 plus 60 to 90 minutes of labour). The power outage post walks through the surge setup that prevents the next round.
Stop and call a Sudbury technician when
You see water on the floor, not just inside the tub. A leaking pump, hose, or housing crack can soak a basement subfloor in under 30 minutes. Pull the breaker, mop up, book a same-day visit. If the flood happens after Saturday 3 PM or on Sunday, our Sudbury emergency appliance repair guide walks through the shut-off and damage-limiting steps to take before we open Monday morning.
You hear bearings grinding or rattling under load. A failing pump bearing will eventually seize and lock the motor. The sibling washer not spinning guide covers how motor and bearing failures often follow drainage problems by 6 to 12 months.
You smell burning plastic from behind the washer. Unplug it. Do not run another cycle. Wiring-harness melts happen on 10+ year-old Whirlpool Direct Drive and Maytag Centennial models. Fire risk once they start.
The washer is more than 12 years old and the pump motor failed. A 12-year-old machine with a fried pump is rarely worth the $200 to $300 repair. Pump plus likely-next-year tub bearing crosses 60% of a new mid-range washer. Read repair vs replace first.
Why washer drainage problems cluster in Sudbury homes
Three patterns drive these calls.
Hard-water sediment in the standpipe and pump. Sudbury municipal water runs 60 to 120 mg/L of total hardness. Rural wells in Hanmer, Val Caron, and Capreol cabins push 80 to 200 mg/L. That mineral content combines with detergent residue and lint to form a grey paste that coats corrugated drain hoses and clogs pump filters faster than soft-water cities. We see hard-water drain calls at roughly 2x the rate Toronto or London ON colleagues report. Full mechanism in how Sudbury hard water damages your appliances.
Older galvanized standpipes in Donovan and Flour Mill. Many 1950 to 1970 homes still have 1.5-inch galvanized standpipes instead of modern 2-inch PVC. Narrower bore plus 65 years of internal scale plus a modern high-efficiency washer pushing 25 to 35 gallons in 90 seconds equals an overflow at the standpipe rim. Re-piping to 2-inch PVC is a one-time $300 to $600 fix.
Hydro One brownout recovery on rural feeds. Same pattern that drives our freezer and fridge calls. Every storm-restoration cycle drops a few washers into error-locked states needing the 60-second power-cycle reset from Check 6.
Most washer not draining in Sudbury cases are 30 to 90-minute repairs once we have parts on the truck. See washer and dryer repair for the full coverage area.
