Is it spewing (love the phrase) when filling up? In which case is there a problem with the bit where the water comes in?
Is it spewing all the time...has the hose connectory thing (attached to the water pipes) come loose?
Is it spewing on spinning/emptying - therefore is your waste pipe bent/blocked and is causing an overflow?
Does it have a filter you need to de-clog - does this need doing as cloggy stuff causing a backup leak.
BTW I am not a plumber/washing machine expert at all - tis these are just what I would look at upon first discovering a spew. Any of the above I would be able to have a stab at rectifying myself. If something else can you google it. More info on here may get someone with experience able to advise you. So when/where from/what quantities/hot/cold/clean/dirty water?
Have you checked the hoses are connected properly at the wall? And that there is no dodgy connection at the washing machine end of the inlet pipe. Is the water coming from the bottom of the machine? Is it coming at "mains" pressure - ie how fast your taps run - or is it more of a dribble?
We had the same with the dishwasher. Dh u screwed the side panel so he could see where the connecting hose was supposed to join the inlet pipe of the machine. Hose had come lose and he shoved it back on.
