Re: LG F1403RD washing machine – drum bolt
Yes. That’s all very well but the rotor is splined in the centre and will come loose again. A new rotor is about £50. Fortunately the splines on the shaft are hard whereas the rotor splines are into a nylon bush. I fell into the same trap thinking it was only a matter of tightening the bolt.
Re: Miele Novotronic T7644C – stopped drying
I figured out how this works to help others. The main board turns the heat on by sending 12V to the relay K1 mounted at the top of the rear panel inside. If the machine is not heating first check that 12V is getting to the coil of this relay. When the relay is turned on and the heater is working the heat is measured by a thermistor on the real panel. This thermistor, 2R30, is about 60k when the machine is cold and should reduce in value as it heats. If it is short circuit hten no heat. If it is open circuit you will blow F1. For safety there is a cut-out on this paneel, F1 should be a short circuit. If it is open circuit replace it. The exhaust temperature is measured by a sensor near the door. You need to remove the front panel to replace it. It measures about 15K cold and reduces as it warms. If all is OK but the there is no heat going to relay K1, remember that the machine senses moisture so you need to use the dry program that doesn’t sense moisture. if it still doesn’t start heating and there is a clunk every time the drum turns then the humidity sensor brushes are worn. Miele say that this will not stop the heating. Shame on them it certainly does! The processor does a check on these brushes at start-up.The clunk is a design feature to tell you when the brushes are worn. If you lift the brushes off the drum and place them a wet cloth, you can confirm that the machine will now heat after restarting it. If the lights all behave properly you can be pretty sure that the processor board is in good helath so don’t let a local “replace everything” merchant mislead you and chage you another £150. All the parts for this machine are expensive. It seems they have a minimum of about £55 for a part. Any repair almost pays for a new machine!
