    Hi all,

    washing machine has stopped mid cycle with E20 error code. No blockage found in pump drain and now when switched on, pump runs for a short while and then the start button resets and starts flashing.
    Do I need to replace the pump?

    Hope someone can help.

    Thanks
    Steve

    Hi Steve.

    Do you have the product number? It is on a rating plate behind the door & begins with 914.

    Also, I assume that as you checked the drain filter the machine was therefore empty of water. If so, when you tried afterwards, did the door lock & did it start to fill with water.

    Let me know.

    HI

    thanks for responding.

    PRN is 91400209601.

    After checking drain pump, machine did not fill with water, it just kept returning to start button flashing mode when start button activated.

    Having switched off at power socket overnight, set the machine to rinse cycle today.

    It filled with water, drained fully and rotated the drum.

    Seemed to stick at this point and after about 5 to 10 mins of the pump running with no water in drum it cut out and displayed E20 again.

    That is odd that you say it has fully drained then displayed “E20”. Did the rate of drainage appear unduly slow? Does it drain into a sinktrap?

    It might be worthwhile putting the drain hose into a bucket, filling the machine & then putting it onto drain & seenig how quick/slow the water drains.

    The machine obviously thinks it isn’t draining quick enough or at all. “E20” usually appears after 10 minutes of drain pump action without water being drained to reset the pressure switch to empty. It is unlikely the pressure swich is faulty. It could even be a blocked air chamber or air hose. Take off the thin black rubber hose from the pressure switch & blow down it to see if it is clear.

    Please ensure that any work you carry out is done with the appliance unplugged from the mains voltage supply.

    Hi,

    Thanks for this info SpinDoctor.

    Presumable the pressure switch and air hoses are accessed from underneath.

    I’ll have a look and let you know.

    Hi again,

    Thought about your wise advice SpinDoctor.

    The missus been trying to save the environment and tells me she hasn’t done a wash over 30C for a while.

    I ran a 95C empty wash cycle and this has worked. I presume the hot water has melted some of the crud in the pressure bowl maybe.

    Any wise ideas for breaking this crud down further without having to un-plumb and dismantle the machine?

    Or am I going to need to manually intervene in the near future?

    Steve

    PS. Missus re-educated.

    Hi Rudders.

    I’m pleased that, touch wood, the maintenance wash has done the trick. All I would suggest further is obviously to regularly maintain the drain filter & to run a 95 degree cycle without pre wash or any other option, no laundry with a cup of soda crystals poured directly into the drum, not the dispenser. Let the cycle complete & then check the drain filter. Do this maintenance cycle about once every six months.

    Good luck.

    Hi SpinDoctor,

    I have this morning done as you suggested and blown down the 2 air tubes from what appeared to be 2 pressure switches.

    I cannot believe the amount of crud that ended up in the drum after doing this, clearly as you said, this was the problem.

    Have done 2nd boil wash now and the matter is sorted and the machine fills with far less water during the wash cycles etc etc.

    Many thanks SpinDoctor for pointing me in the right direction. I greatly appreciate this.

    Do not use soda crystals. This is a myth perpetuated by Kim and Aggie. Use a Whites Biological powder such as the green box of Ariel for best results. Do it monthly.

    For what reason would you not use soda crystals. I have been given this advice for years before anyone had even heard of Kim & Aggie by many people higher up the domestic appliance manufaturers food chain than I (I.E. various technical advisers, senior techs, centre managers etc). I have used this method in my own machine over the years & it is in tip top condition after 7 years & 3 kids later.

    I know this is what the instruction booklets say in some cases in that to use a whites bio powder however.

    Cheers.

    Well, having a Diploma in Detergent Training from Proctor and Gamble does mean I know what I’m talking about. If P+G say it doesn’t work (and they should know what they’re talking about…..) I’m quite prepared to believe them.

    What are the detergent properties of Soda Crystals?

    I am not disputing your knowledge, just trying to expand my own by asking questions as I believe this is how we all learn in life. Having said that, you say that P&G recommend to use a whites bio detergent. Call me cynical but they are hardly likely to say otherwise, I feel.

    The detegent properties of soda crystals are, I suspect, virtually zero.

    I guess at the end of the day people have differing ways on tackling the same problem. I have heard people using citric acid (a trick old AEG techs will confirm),bleach & vinegar amonst other things.

    Whatever works, I suppose.

    Best wishes.

    Good article here:

    That section has some other good stuff on cleaning in there as well.

    An informative review, Penguin. Like I said, please don’t think that I am disputing your knowledge which I am sure is comprehesive. I have a naturally inquisitive mind & like to ask questions. I guess that is why we do what we do.

    Good luck Penguin.

    Me too!

    Soda crystals can be just as effective for a ‘service wash’ and have the added advantage of being fully bio-degradable unlike bleach based detergent. So say various unbiased web sites on the subject when googling ‘soda cystals’ anyway? 😕

    My mother and grandmother always used soda crystals for cleaning away gunge and grime including poking some down the sink with a kettle of hot water to clear the u bend. Maybe Kim & Aggies parents did the same? 😉

    Mind you, my mother (god rest her soul) never had a washing machine. If she did she’d probably have lobbed some soda crystals in it I expect? 🙂
