Hi. Has anyone had problems with their Bosch washing machine continually being slower through the programmes.? We have double checked the water supply and the machine fills ok, and no kinks in any hoses. Have checked the outlet and it drains ok when it gets there. Also checked and cleaned the filter. The machine seems to hesitate for periods of 30 secs to a minute during the wash, the wash light flashes and you can hear a gurgling within while it hesitates. It does this even with half a load and minimum detergent, usually adding 15 mins to a wash cycle and missing out the spin but still draining. Any ideas.? Thanks.
