Frequently asked questions
Can I keep using a Samsung washing machine with UB showing?+
It is usually better to pause use until you have completed the safe first checks for UB, then test the machine with a short programme.
Will resetting clear UB for good?+
A reset may clear a temporary interruption, but if UB comes back after the first safe checks, the underlying fault still needs attention.
