try over in the appliances section, they might have a better idea.
that said, and just throwing ideas out there it might be a hose come loose, the pump knackred, the lint trap not tightened properly, a leaking seal, a dodgy solenoid to name but a few..
only way to find out is to strip it down and have a look.. but check the inlet hosest ( tight and not split ), drain hose ( not blocked or split ) and lint trap ( not full, tight, emergency drain hose etc ) before resorting to stripping it down.
