Hi there,
I have found another solution.
It happenz that some things or just mushrooms build in the pump and blocks it.
Than there is a automatic routine, that the pump stops and pull back some water to pull out the shit.
So just only switch off the power and fill the maschine with water, about 3 or 5 litres, till the ground is full of water. Than the blocking thing should come out by waterpressure..
Just first try this, it is much easier... ;)
best regards Olly
