Montpellier intermittent leak

[Googleit]

Montpellier MW1045W leaks intermittently. Seems to come from the left hand side underneath nearing the end of the cycle. Filter and all pipe work is clear of blockages. Machine is level. Doesn’t happen every cycle and am using the same amount of detergent I have always used. When it does leak it is substantial and is often quite soapy.

machine is under warranty however engineers have been out and are at a dead end as to what’s causing it, they seem to imply using too much detergent however I’m going off the detergent manufacturer instructions and have used the same amount for the past year with no issue.

I have taken the lid off and it appears to come from a breather opening in the dispenser housing that runs out into the cabinet and onto the floor.

any ideas very much appreciated

Based on the following before we start. Chinese made, looks as though its a discontinued model, only found a door seal and no other parts listed which gives the impression it was not imported for very long – all cheery stuff and all pretty typical so completely in the dark on this one. Could well be very similar to the 10kg load Bush model wmsaex1016w which is also Chinese and also with no parts listed so no help there!!
Ok, based on not much info available. What follows is what you can look for no matter how daft it sounds (I`ve got no part pictures no nothing / sod all other than a picture of a door seal) 1) do you have soft water? = over frothing 2) you say it leaks from a breather which presumably is part of the soap dispenser`s moulding (so with NO additional hose from the dispenser to the top of the tank) so check the hose from the dispenser to the tank, remove the draw – anything blocking it and are the water spray holes all clear? Trapped piece of cloth where the dispenser hose joins tank is not overly common – this gives you either a blockage and hence a flooding leak everytime it fills OR the much more subtle part blockage fault of a “vaccum” fill leak where the machine fills ok until a fill further on in the cycle, and so the machine has pumped out then refills, but the air cannot get out of the tank causing the incoming water to leak out of the dispenser since it cannot go elsewhere – a slim possibility admittedly. Had that one a few times but on old machines which yours` isn`t.
3) the pump filter is part blocked.OR the sump hose – part blockage by a sock where hose joins to bottom of tank which would give you poor pump out and a similar effect due to point 4 since I am prsuming the air trap chamber is also part of the sump hose
4) the pressure switch hose has a fine split/ tiny hole this causes the machine to over fill by filling up the whole drum with the flooding outcome via the dispenser BUT you can also get the split where this thin hose joins to the pressure switch so as the machine fills, and the whole tank sinks down due to weight on the suspension springs, that the hose pinches up the split and the water does turn off the filling but at increased height – rare but not unkown based on my own experience on Chinese and Korean made stuff. Seems to happen with horizontal mounted pressure switchs.
So some Pointers to check.
