    Re: Neff oven U1661N2gb06

    “444” means its in the shop display mode. This can happen if the customer has had a power cut or other fluctuations in supply. To return to normal operation turn the selector from the off position one click clockwise to position 1(circotherm/fan). Within 6 seconds you have to turn the knob from position 1 to position 2 five times (forward to pos 2 & back to pos 1 five times). The display will then show “333” to show normal operation. If its the small top oven, use the same proceedure.

    Re: Bosch SMI 2022 – wiring problem/replacement?

    I’ve done a few over the years & I can confirm its not the easiest job to do. I wouldn’t bother if you dont have access to the wiring diagrams because it is possible & very easy to put the connections in the wrong places if your concentration lapses (all the connections are the same, so any wire will connect to any component, unlike the modern stuff where the plugs are keyed & usually only connect to the correct component). If you are going to attemp it, my tip would be to take several digital photos of the wiring before you start. At least this way you would have something to refer to if you can’t remember where you just pulled that last wire from!

    Re: Bosch upright freezer running continuously

    I dont think anyone has or would suggest shorting out any safety devices. I would not try this method at all, it could be very dangerous. If there is a fault on the PCB, the heaters could remain on causing a fire if you have shorted out the safety fuse. ❗ If in doubt, call in an expert. Your safety is paramount.

    Not a big job. Motor off, replace rear bearing shield (complete with brushes), click new brushes into place. Refit motor, job done!

    Its only a pig if you are doing the bearings as well. Lying the machine on its back is the only way of getting the tank front/weight back on (unless you get someone to hold it whilst you refitt the band clamp). I usually remove the dryer duct completely so its out of the way. The spider is riveted to the drum not bolted. I’ve always replaced the spider & drum at the same time with the fixing kit.

    I’ll second that. It is a pig of a job. I think the tank is made by wilkinson sword. Count your fingers afterwards 😆

    You say at some point in the past that you have squirted hot water into the evaporator! This may have caused the thermal fuse to go open circuit. If the thermal fuse is open circuit, the defrost heaters will not operate causing continuous problems with frost build up. You can identify the thermal fuse by looking for a black oval tube shaped device about 15mm long pushed into the fins of the evaporator with 2 black wires leading to the connection block. It should have continuity when tested with a multimeter.

    Hi iodom, there are about 40 BSH group factories world wide. Take your pick! All the top end stuff come out of factories in Germany. IMO pound for pound, I would choose a Bosch dryer every time. Pay a little bit extra & get a much better machine. 😀

    Re: Bosch upright freezer running continuously

    The evaporator has probably frozen over again. You will need to completely defrost the unit. 24hrs is not always enough as the insulation is very efficient. Its not the easiest to defrost. You need to make sure all the evaporator is completely frost/ice free before switching back on. Although it may look clear from the front, there is probably an ice blockage around the circulating fan at the rear of the evaporator. Best to leave it switched off for a few days the with door open. When you are happy its completely defrosted, check to make sure the door is striking the door switch correctly as this operates the fan. The fan should run as soon as you close the door although does not always run continuously. A re-gas isn’t always a good idea & is only a short term fix. If the original gas has escaped, then there must be a leak & can be difficult to cure.

    Hi iadom, I can asure you Bosch no longer buy in badged machines from Gorenje. All the Bosch dryers are now made in a Bosch factory! 😀

    Re: siemens washer dryer topline

    Hi, when the machine has stopped filling, listen carefully. Do you hear a relay clicking & no drum action? If you hear the relay operating but no motor action, then more than likely the motor brushes have worn. When the machine cuts out, do you get a series of flashing status LED’s. If so, which LED’s are flashing. This is a fault code & will point you in the right direction to a correct diagnosis. On your model, the carbon brushes come fitted on the rear bearing shield of the motor. The siemens part number is 496876.

    F43 means no tacho signal from motor. Check harness from motor to main power pcb. Check motor carbon brushes. Worst case it might need a new motor or power module.

    Re: Siemens SE20790GB/04

    Its quite normal for this machine to use the same water for the main wash from the pre-wash cycle. If the turbidity sensor senses that the pre-wash water is clear/not dirty, it will continue into the main wash without draining & refilling (to save water). It will however drain the water if the sensor senses cloudy/dirty water & refill with clean water. Leaving 1 minute in the display & sometimes not heating usually indicates that the left hand side water chamber & pressure switch assembly & or the sump hose is blocked with deposits. This causes a lack of water entering the sump causing cavitation in the circulation pump. This then stops the pressure switch on the heater activating due to a lack of wash pressure causing the intermittant heating problem. I would’nt invest in new modules until you are happy that the machine is filling correctly.

    If you mean the valves on the side of the water softener unit, they are different. One is the outlet valve for the water chamber & the other is the regeneration valve. You may find a third valve on the rear of the water softener which is the raw water valve (to allow a certain amount of hard water into the wash). Regen valve 166875, outlet valve 166874, raw water valve 174815.

    Re: Siemens WDI 1640 Washer/Dryer Won’t start Program E14

    Yes, I have had the odd NTC fail & cause intermittant problems. They can go out of tolerance. You can order it online from siemens http://www.bshcustomerservice.co.uk click on spare parts.
    Or if you prefer by phone tel 01450 2655 (Ireland spares dept).
