The short answer
An ADC EWH washer that will not drain is blocked far more often than it is broken, and the blockage is usually in the first place you can reach. Water leaves a washing machine through a filter, a pump, a hose and a standpipe, in that order. A failure anywhere in that chain looks identical from the front, so the fix is to work along it from the accessible end rather than to guess at the pump. The table below lists one model for this family, so there is no second configuration to rule out before you begin.
What you observe on these models
- The drum is full of water at the end of the cycle — Nothing left at all, so the blockage is total rather than partial.
- The machine drains slowly and the cycle over-runs — A partial restriction, which is what a filter half full of lint does.
- The pump runs loudly but no water moves — The pump is being asked to work against something, and that something is usually visible in the filter housing.
- Water drains and then comes back into the drum — That is a siphon or standpipe problem outside the machine rather than a fault inside it.
- NEAR MISS — the drum drains fine but the load is still wet — That is a spin fault, not a drain fault, and the cycle page for this family covers it.
Causes, most likely first on the EWH family
- The standpipe or waste connection blocked — This is outside the appliance entirely, and it is the cause that produces water coming back into the drum — a symptom no internal fault can create. On the EWH family this holds without qualification, because the family covers one configuration rather than a spread of them.
- The drain hose kinked, crushed or blocked — The hose is behind the machine where it gets trapped when the appliance is pushed back, and a crush that does not fully close the hose gives the slow drain rather than the total block.
- The drain pump impeller jammed or the pump failed — An object past the filter reaches the impeller and stops it, which sounds exactly like a running pump doing nothing, and it is the residual once the chain above is clear.
- The pressure system misreading the level — A machine that believes it is already empty stops pumping while the drum is still full, which is the one cause on this list where the pump is faultless.
Check in this order on these models, and why
- Pour a jug of water down the standpipe and watch it clear — Third, and it decides whether this is an appliance repair at all.
- Pull the machine out and run the hose through your hand along its length — Second, because a hose fault is found without any tool and explains slow drains.
- Listen for whether the pump runs at all during the drain stage — Fourth, because silence and noise mean different repairs and the checks above have to be clean first.

Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A drum full of water is heavy and the water can be hot: let it cool, and drain it into a shallow tray through the filter rather than tipping the machine. Work on a dry floor and keep the cord and the outlet away from the water. Leave the door interlock as fitted; it keeps the door closed while the drum still holds water.
When to call a technician
Call a technician when the filter, the hose and the standpipe are all clear and the machine still will not drain, because the next step is inside the cabinet. Call sooner if water is escaping onto the floor while the pump runs, or if the machine trips its circuit during the drain — a pump that is drawing enough current to trip protection is a fault to leave switched off rather than to retry.
