Washer Leaking
A puddle on the laundry-room floor is the kind of problem that gets worse fast. Some leaks are obvious — a hose nobody tightened. Others come from inside the cabinet and can warp a floor in days if ignored. Here’s how to figure out which is which before the floor pays for it.
What's probably wrong
The trap on washer leak calls is that “leaks during spin,” “leaks during fill,” and “leaks constantly” point to different parts. A wrong-part swap on a tub seal costs $300+ in labour that didn’t fix anything. A proper diagnosis takes about ten minutes if the tech knows where to look — and which cycle phase to watch.
The diagnosis matters because some of these are 15-minute fixes (a loose hose, a replaceable gasket). Others mean pulling the drum out (tub seal, drum bearing). The wrong assumption — “I’ll just replace the door gasket” — wastes money if the actual leak is coming from a worn pump seal a foot further back.
The most common causes
Ranked by how often we see each one. The diagnostic that actually matters isn’t a guess from a list — it’s a tech listening to your machine, looking at the install, and checking the right things in the right order. But it’s useful to know what’s on the menu.
Door Boot / Gasket Tear (Front-Loaders)
Water shows up: in front of the unit, often during the spin cycle. The rubber door gasket gets nicked by bra wires, zippers, and coins that work their way under it. Even small tears leak. Inspecting the gasket with a flashlight catches most of these in under a minute.
Water Inlet Hose Loose or Failing
Water shows up: behind or to the sides of the unit, during the fill cycle. The cold and hot inlet hoses run from the wall taps to the back of the washer. Connections loosen with vibration; hoses themselves crack near the fittings. Universal failure point on washers more than 5–7 years old.
Drain Hose Loose or Damaged
Water shows up: behind the unit during the drain or spin cycle. The drain hose runs from the back of the washer up into a drain standpipe or laundry sink. Works loose with vibration, cracks at the corrugations with age.
Drain Pump Leaking
Water shows up: underneath the unit, often dripping out the front bottom. The seal where the drain pump motor meets the housing wears out. Sometimes preceded by louder pump operation in the weeks before. Pump usually needs replacement.
Tub Seal Failure (Front-Loaders Mostly)
Water shows up: underneath, often only during high-speed spin. The seal between the inner drum and the tub bearing has worn out. This is heavy labour — the drum has to come out. Often a “consider the age of the machine” conversation more than a routine repair.
Detergent Dispenser Overflow
Water shows up: dripping from the front-top of the unit, during the fill phase. The dispenser drawer or its housing is clogged with detergent residue, water backs up, overflows down the front. Cleaning the drawer often fixes it; sometimes the assembly is cracked and needs replacement.
Before you call
A few things worth looking at before you book — they narrow the cause and can sometimes resolve the simpler ones outright:
Run a short cycle, watch with a flashlight. Front, behind, or underneath? Different locations mean different causes — and the tech will move faster knowing.
The taps on the wall and the back of the washer. Gently snug any that have backed off — no wrench needed. About 1 in 5 “leak” calls is just this.
Pull the rubber lip back, look for tears, cuts, or stuck objects. Shine a flashlight in. A nick the size of a hair will leak under pressure.
If it’s caked or moldy, water can back up. Pull the drawer (most click out) and rinse it under the tap.
Especially if the leak is somewhere you can’t see. Most washer floods start small and become major over hours. Closing the taps stops the bleeding while you wait.
Why a real diagnosis matters
Here's the math customers don't see: the same humming-pump symptom can come from at least four different parts. If you guess wrong and swap the pump when it's actually the lid switch, you've paid for a part you didn't need, the symptom returns, and you call us anyway. A tech who knows your specific machine usually has the answer while they are still standing in front of it.
Reads error codes accurately. Manufacturer codes are routed differently between brands. A code that means "drain fault" on a Samsung points to a different starting test than the same fault on an LG.
Pre-sources the right part. Your specific make + model + symptom narrows the most-likely part to one of two or three. The common ones are the ones worth carrying — most washer drain repairs are one visit.
Catches the secondary issue. A failed drain pump on an older washer often coincides with a worn-out drive belt or lid switch nearing end-of-life. Replacing both at once is one service call instead of two.
Tells you when it's not worth fixing. Some machines aren't. We'll say so without billing for the diagnosis when the honest answer is "buy new."
What the repair typically costs
Kodiak quotes labour as a flat rate per repair type, after diagnosis but before any work begins. Parts are quoted separately on your invoice. Typical labour ranges:
Most washer leak fixes — door gasket replacement, inlet/drain hose swap, drain pump replacement, dispenser repair — fall in the $220–$350 range for labour. Parts are quoted separately when needed; gasket and pump pricing varies considerably between brands (here’s why).
Heavier labour — the drum has to come out. Quoted after diagnosis, and the moment to honestly weigh repair against replacement on older machines.
