This washer dryer has a dual water inlet valve, one feeding the washing machine, the other the tumble dryer. If your machine is washing normally - including rinse out fluff and warm air drying - it's likely the solenoid operating the second valve has failed - specifically gone open circuit.
First, disconnect the power. You can access the valve from the back at the bottom; undo the hose connection (turn the water off!), remove two torx screws, pull the latch at the centre top forwards slightly, lift the plastic panel up slightly and then wriggle it free. There are two hose connections and two electrical connections. Mark one pair with tape to prevent them getting mixed up.
If you have an ohm-meter, disconnect the electrical connectors and check the resistance of each solenoid. Mine was about 3.6k Ohms with the faulty one open circuit.
The replacement valve costs about ÂŁ60; disconnect the wires and hoses, and replace with the new valve.
If you want to run an extra test to be certain the valve is the problem, run with both water and the two connections disconnected. Be careful, the solenoids run at 240v so ONLY do this if you are CERTAIN what you are doing. Disconnect the power and connect an AC voltmeter to the connector - if you have one with standard prods, they can be pressed in to the connector sideways. Reconnect the power and run a drying cycle and you should see 240v at the connector during the first few minutes before the error alarm. If you don't see this, there problem may lie elsewhere.
