Bosch Exxcel washer/dryer problem!?

My Bosch Exxcel Washer Dryer (WVD2452BGB) has a problem. The washer heater element seemingly broke, so I replaced it. Now when I try a wash cycle, it seems to take longer than expected, constantly run water through the detergent drawer (on the main compartment), and won't drain properly - probably because of the water from the detergent drawer constantly running. Also the water doesn't feel warm at all either.

Any suggestions as to why this would be?

Thanks in advance.
