im having a couple of problems with my dishwasher. 1. it leaks water from the prewash and wash stage 2. Every few times either during the prewash or the wash stage the machine will stop washing and (depending on whether its the prewash or wash stage) the light at the stage will start to flash. If i turn it off and turn it back on it happens again. i usually have to leave it over night before and it might work the next day. Then it only takes a couple of days before it happens again
