I have an integrated CDA WC140 and it seems to stop early in each cycle (P1-P4). I’ve had it in our holiday home for 3 years so it isn’t used all the time. When it stops it leaves water in the bottom and there aren't any beeps or lights. Then I can run P5 and it rinses, successfully drains, beeps when it's finished and the end light goes on. Any idea why it won't finish the other cycles?
