I have a Zanussi Lindo 300 washing machine, to which I've had an engineer out on two occasions due to oversudsing.
When I looked this up on Google I came across this site but the discussion was 2014, even so it was confirming what the engineer had told me.
Unfortunately I still have this problem and I have to use so little detergent that stains etc., are not removed. About 15ml - 20ml max.
This machine recommends liquid detergent although I see where you say use a non bio powder instead.
When I did try powder I was getting white patches. I changed to Persil instead of the recommended Ariel, which seems slightly better.
Obviously I am not using 60 and 90o washes too often as it takes this to dissolve any detergent.
I do not overfill the machine either as there are just two of us now.
Today I washed four towels at 90o , 1, to just rinse the towels through and 2, to clean the machine at the same time on a cycle which was over 3 hours long!
I used NO detergent and it still foamed to the brim although I did not have an overflow like last time.
I had to then run yet another program to get enough water going through until it became clear.
I am in a soft water area and dose with that in mind.
The engineer advised to run at 90o at least once a week although the instructions say monthly or a few times a year as he did say these detergents adhere to the machine on the lower temperatures and so build up.
Why are they made this way?
This is using more electricity and water , not good.
Is there an answer to this and has anyone else had this problem please?
