After some mains high water pressure problems in our house, my 10 yr old Bosch has stopped working. The "Active" light is flashing. Is that because I now only have a cold water supply connected, or is it because the pressure is too low? There is no water entering the machine.
I used to have both Hot and Cold hoses connected, but the high pressure burst the seal on both connections. The mains water pressure is back under control, but I have only been able to replace 1 seal at the moment. The cold water hose is connected and turned on.
