Questions people ask
- What does SUD mean on a Whirlpool washing machine?
- Too much foam, so the machine has paused to deal with it before carrying on. Yes. Nothing is broken. The machine is running a suds reduction routine, which adds rinses and can stretch the cycle by an hour or more. It usually finishes on its own if you leave it alone. Start here: use less detergent, and halve what you think is right.
- What does SUD mean on a Samsung washing machine?
- Foam has built up faster than the machine can clear it, so the cycle has stopped part way through. Yes. Nothing is broken, and the machine is already dealing with it: extra water goes in and extra rinses run until the foam collapses. What this costs you is time, sometimes a great deal of it, rather than money. Start here: check you are using he detergent.
- What does SUD mean on an LG washing machine?
- There is too much foam for the machine to rinse and drain normally. Yes, and in most cases the best thing you can do is nothing. The machine adds water and rinses until the foam settles, which stretches the cycle but harms nothing. What it will not do is spin properly until the foam is gone. Start here: check the box says he.
Do not see your machine? We publish a brand only once its codes are confirmed against manufacturer documentation and a second independent source. That is slower than guessing, and it is the whole point of the site.
This is not a coincidence of one code: we compared every code that appears on more than one brand and found that several mean the opposite depending on the badge.
