I have a Bosch dishwasher, there is still water in when the cycle has finished. plumbing has been checked and cannot see the problem. Also have a hotpoint washing machine, think the filter is blocked, as again water left in washing machine, even putting it on wash with no soap powder there is dirty water left, but I cannot find the filter to check! Any ideas where it is? It is not visible. It is a Hotpoint First Edition 800.
