I just got a ntc Temperature Sensor for a W1213 Washer and was wondering how easy it is to change??
Make sure there's no water in the drum.
Important! Switch off and remove plug from electricity supply!
Remove front base plinth (pulls off use a plastic lever if necessary - one inside soap dispenser drawer). Remove front panel of machine (torx screws at bottom, torx screw under drum. Slacken wire around door seal and remove (hook it with a smallish screwdriver. Do not damage seal. they are ridiculously expensive).
Unclip seal from front panel. Pull front panel out from the bottom, then down. Reach around the now detached front panel and unclip door lock wiring). Put panel somewhere it won't fall over.
Locate element underneath drum at the front - oval rubber with connections to it.
Temperature sensor is in the middle of the element. Unclip the plug from the back of the sensor. Gently but firmly pull the sensor out toward you. It's just a friction fit in the rubber. you can use narrow pliers but don't crush the socket of the sensor. If you want to test it, put a multimeter set to ohms on it. Resistance will vary under say a hot or cold tap/faucet.
New temperature sensor will push fit into old hole - moisten case first to make it easier with a tiny bit of washing up liquid (or spit!). You might want to test it first as above.
Reconnect wires, lock harness, front panel, attach door seal, attach door seal retaining wire, screws, base plinth.
Congratulate yourself on saving shed loads of cash.
