If the machine still has water in it, lower the outlet hose
into a bowel or bucket until you have removed as much water as possible, then lean the machine forward and remove the rear panel, you should be able to see the water pump attached to the end of the outlet hose, either disassembel the pump
or remove it completley, there is a cooling fan attached to the pump, to check that the pump is blocked or partialy blocked move the fan slowley around, if there is a blockage in the pump you will feel it, some times coines and other bits get in the pump, remove them and it will solve your problem
