The short answer
Most washers heat their own water with an element in the tub, so a cold wash on a hot programme is a heating fault — and on a machine that heats, the cycle usually still completes, which is why it goes unnoticed for months. On a Criterion scale and detergent residue insulating the element 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. Confirming the fault and checking the supply are owner work; the element, the thermostat and the control are not.
What the machine is doing
- Greasy stains and collars stopped coming clean — Temperature does work nothing else does; losing it shows first on oily soil.
- A heating error code appears part-way through — The control has timed out waiting for a temperature rise.
- The door glass stays cold on a hot programme — The simplest test there is, and it needs nothing but a hand.
- NEAR MISS — Everything is cold and the machine also fills very slowly — Check the hot supply and the inlet screens first — some installations feed hot water directly.
The ranking
- Scale and detergent residue insulating the element — First on this brand: 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. In hard water an element grows a crust that acts as insulation, so the machine heats slowly, times out, and carries on cold.
- A hot-fill installation with no hot water reaching it — Second: Where a machine is plumbed to a hot tap, a closed valve or a failed household hot supply removes the heat without anything in the machine failing.
- An eco or cold-wash option that is doing what it was asked — Third: Eco programmes deliberately run far below their nominal temperature for much of the cycle, which owners frequently read as a fault.
- A failed or heavily scaled heating element — Fourth, and the last to suspect: Elements fail open, and in hard-water areas they scale until the heat cannot reach the water; both leave a cold wash with no other symptom. The drivetrain is simple, which makes it durable — it is a real cause but rarely the first one.
The order to work in
- Ask how hard the local water is and when the machine was last descaled — Hard water plus no maintenance wash in years is the most likely explanation on an older machine. It goes first because it is the cheapest thing to rule out and it decides which half of this list you are in.
- Check whether the machine has one inlet hose or two, and that both taps are open — Two hoses means a hot fill exists and the household supply is part of the diagnosis.
- Run the hottest non-eco programme the machine offers — If that heats properly, the machine is working and the programme choice was the issue.
Hands-on checks
- Run a hot maintenance cycle with a descaling product, empty — It will not revive a failed element but it will restore a scaled one, and it is worth doing before any part is ordered.
About 10 min
- Open both taps fully and confirm hot water arrives at a nearby tap — If the house has no hot water, the washer is reporting a plumbing fault rather than an appliance one.
About 10 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 first
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.
When to stop and call
Call once a plain hot programme has been run, the supply is confirmed and the door still stays cold — the element, the sensor and the control all sit behind panels with mains voltage on them.

The limits of this page
This is the family-agnostic page for Criterion washers. 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.
