So, what were you saying?
What I am saying is that Fisher and Paykel acknowledge there is a problem with fabric conditioners and detergent when they come into contact with each other - so much so that they make light of it in their owners manual for top load machines. It doesn't get a mention in their front load machines.
The vast majority of machines today use polymer based outer tubs which seem to attract the gunk...they certainly don't allow it to wash off as easily as enamel or s/steel.
Couple this with less water at lower temperatures and you have the potential for a problem. Add into this the generally more 'gentle' chemical nature of liquid detergents compared to powders and the problem is exacerbated.
Additionally, I will almost guarantee that people in general have not reduced the amount of conditioner they are using in HE machines compared to 20yrs ago. Most will pour it direct into the cup in the agitator or into the section of the drawer without a second thought. Well less water means less needed, but it is like banging your head against a brick wall trying to educate the public.
Oh, and powders are far far more popular here than liquids outselling them by at least 2:1. Up until I found this site I had never heard of anyone having a stinky front load machine and only knew of the 'grey gunk' - scrud - from people who had used the following in combination:
- cold water
- liquid detergents
- fabric conditioner.
..and generally in a top load machine. I first experienced it in 1995 when I washed my (white) work shirts in a friends hoover top loader....I turned the hot tap on and put powdered Omomatic in...when I took them out, they were covered in grey globules of sticky goo..... Turns out she was a cold water washer with liquid detergents AND fabric conditioner.
I, and many others on here, wash in warm/hot water. My mother doesn't go lower than 30c and I generally don't either. Cold water washing is something that Australians have done, with increasing incidence, for 20-30yrs but mainly in top load machines as most European front loaders sold here only recently started offering a cold option and one of the benefits of a front load machine was you could warm/hot wash with only a small amount of hot water/impact on your electric bill compared to a top load machine - though I am not trying to inflame that debate, bare with me...
Combine this with the use of powdered detergents and warm/hot washes in front load machines and you have next to no incidence of 'stinky washer' as liquid detergents have really only started to become available, on our market, for front load machines over the last 10yrs or so....but at least 75% of the market is still powder/front loaders.
Now with top load machines, the majority of washing (with an increasing incidence), has been cold water and with powder. I would have to ring a washing machine repairer to find out, but I would bet that there is an increase rate of gunk in these machines when fabric conditioner is used in conjunction with cold water and liquid detergents...
