On a washer the door does more than close: it locks against a drum full of water, it seals against pressure, and on a front-loader its bellows is a wear part that collects everything the machine washes. On a Criterion grit, hair grips and coins in the bellows fold comes first, because a value-tier build puts the cheap wearing parts — filters, hoses, seals, screens — in the path of everything the machine does, so they are where the fault usually is. Cleaning, catch adjustment and clearing the seal fold are owner work; replacing a bellows or a lock assembly is not.
Signs that fit this page
- The door will not lock, or unlocks mid-cycle — The catch, the alignment or the lock mechanism itself.
- Black spotting and a film in the seal fold — Biofilm in the bellows, which is also the main source of machine odour.
- The door is stiff, drops, or has to be lifted to close — Hinge wear or a cabinet that is out of level.
- NEAR MISS — A leak at the front but the seal is clean and dry — Look at the filter cover; it is at the front too and leaks the same way.
Why it happens, in order
- Grit, hair grips and coins in the bellows fold — Most likely here: a value-tier build puts the cheap wearing parts — filters, hoses, seals, screens — in the path of everything the machine does, so they are where the fault usually is. Anything that leaves a pocket ends up in the lower fold of the seal, where it wears the rubber from the inside and eventually pierces it.
- Biofilm from low-temperature washing and excess softener — Second on the list: A cold, soapy, permanently damp fold is an ideal home for the grey-black film that eventually marks laundry and smells.
- A sagging hinge or an unlevel cabinet — Third on the list: The door is heavy and the hinge carries it; a cabinet standing on three feet twists the opening and the door stops meeting the lock squarely. It sits here rather than higher because a store-brand unit is usually carried home and set up by the owner rather than by a delivery crew, and setup errors survive for years.
- A catch and lock that no longer align — Fourth on the list, and the least likely: A door that has to be pushed or lifted is pulling the lock out of line, and the lock reports a failure rather than closing. The door hardware is light, so it goes out of adjustment before anything electrical does.
What to check first, second, third
- Fold the bellows back and run a finger all the way round — What comes out is usually the explanation for both the leak and the smell. It goes first because it is the cheapest thing to rule out and it decides which half of this list you are in.
- Smell the fold rather than the drum — The odour is nearly always strongest in the bellows, which tells you where the cleaning needs to happen.
- Look at the gap around the closed door — An uneven gap is a mechanical alignment problem, not a worn seal.
The checks you can do yourself
- Clean the fold thoroughly and dry it — Wipe the fold with a damp cloth and check for splits as you go.
Tools: clothAbout 20 min
- Run a hot maintenance cycle empty, then wipe and dry the fold — Reduce softener afterwards and leave the door ajar between washes.
Tools: clothAbout 15 min
- Stop here if the next move needs a meter on live terminals — That is where an owner check ends and a service call begins.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close the taps before any hose comes off, and never bypass a door or lid switch to run the machine open.
Where an owner fix ends
Call when the fold is clean, the cabinet is level, the catch aligns and the machine still leaks at the door or refuses to lock — a bellows or a lock replacement is a job with the front panel off.

How specific this page is
This page covers Criterion washers as a class, not one family or model line. Nothing more specific exists to send you to at the moment; a model-level page, once written, is linked here and is the better answer. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
