    Re: F+P DD603 H Strange fault.

    Whenever I have seen the pumps seized it has been because the outer plastic on the rotor has split causing the rotor to rust and expand.

    If the elements are getting hot and the drawer is drawing about 1 amp when the draw is turned off but with power to it then it isn’t actually powering the element but drawing too much power through the printed resister, if this is the case then you have a blown surface mount diode on the PCB which may have been caused by the rotor failure.

    I assume you have checked the motor insulation resistance, the only times that I have ever had this error on an Electrolux machine have been because the armature short to earth – Maybe I have just been lucky but I haven’t replaced a board for an E51 yet.

    Re: Hollytree_technical 22W fusible resistor where from?

    Technically it’s a buck converter but yes it is a form of sips supply, designed to be used instead of an X2 class capacitor supply.

    Re: Hollytree_technical 22W fusible resistor where from?

    Being able to Identify resisters as a fusible type is something that comes with experience however a couple of pointers for you are:

      If it is directly in-line with the mains input to the machine (especially if it is part of the low voltage power supply section).
      If it has a matt coating as opposed to the normal gloss coat
      If when it is blown you can see a white cement under the top coat

    Fusible resistors aren’t always listed as “Fusible” on websites, you have to look at the data sheets where it may say “Fusible” or “Flameproof coating” or “Failsafe”. To give you a start for reference these ranges are fusible:

      Welwyn ULW
      Welwyn EMC2
      TE Connectivity FRN
      TE Connectivity EP
      Vishay AC0….CS

    You can get them from Farnell, RS, Mouser etc

    Looking at my purchase historys it looks like I may even be using 1W :eeek: 22 Ohm resistors but I haven’t had any call backs so they must have been OK. RS part No: 762-9352P

    Re: HOTPOINTtumble dryers (the belt breaking bearing muncher

    Grind the remains of the shaft off then fit new one as normal.

    Anyone got a list/table/diagram which explains the different belt profiles in a little more depth, I know it has the number of ribs and the length marked on most belts but would be interested to know more about what the letters actually mean.

    Yes, it is front left of the machine, you will see a red rod coming up from the base, this is from the anti flood float and the switch that it activates is also the overfill switch.

    Check the pressure chamber in the left hand side, these gunge up which causes the water entering the machine to back up and activate the anti flood / overfill switch which can sometimes get jammed in the activated position.

    Re: Zanussi ZWJ12591W error

    You will always get the ELE code when you turn it on for the first time after being in test mode, just turn it off then on again as it is nothing to worry about.

    Re: Hotpoint AQ113D697E – Tub Leak

    I am not sure that it is the bearing seal as the level of the water in the hollow goes up and down with the water in the tub, it turns out that it may have been leaking for a long time yet it has no bearing rumble.

    Looking at an image of the motor it looks like the same make/style as fitted to various Bosch machines and that a set of Bosch carbon inserts would fit it.

    Re: Samsung RSA1RTMG

    Well I had a look at it today and the ducks bill was OK even though it didn’t have a slit right across, what I did find was that the top end of the drain hole was frozen over even though the evaporator was clear, now the customer admitted that the unit had been set on -25 and jammed full a few days ago when they first had the fault although it was set at -18 when I went to look and not to badly packed.

    I have cleared the hole and checked that the defrost heater is OK and we are going to see what happens over the next few days but I was just wondering if it was possible to alter the defrost time if necessary in these or if there is any mods to the defrost circuit.

    Re: lamona intigrated f/freezer hja 6015

    If the beko board looks the same then it looks like it uses a capacitor power supply so it would be very possible that it just needs the X2 class capacitor changing – I have not done it on this model but do this repair regularly on various other fridges and freezers for no life faults with considerable success.

    Re: Hotpoint MK6 board dead

    I don’t have a board to hand but would suggest that the 8 pin microchip (possibly a TNY253 or similar) near the small transformer is the most likely suspect (also check the electrolytic capacitors by it).
