Bosch classixx 1200 express WF02467GB 01 water will not stop coming in to powder tray
If it's a slow trickle it is possibly one of the inlet valves letting by. This will either mean replacing the valve or checking that the in water pressure is adequate. If it's a continued flow during a cycle, you have either a faulty pressure switch, a hole in the pressure hose or the pressure chamber is blocked. Check out the last two things first. Disconnect from power, remove two T20 screws from top at back, push the lid back approx an inch then lift off. The pressure switch is situated on the right hand side near the top of the machine opposite the dispenser (It is a round or oval part with wires in the middle and a small black ribbed hose attached at the bottom of it. If you remove the hose and and blow down it, this should give you a good indication of whether the chamber is blocked (with limescale etc), checking the hose for holes is a bit more difficult as you will need to get it off completely. The other end of the hose is attached to the pressure chamber ( white plastic cylinder ) the small plastic parts that it is attached to is quite delicate, so be careful when pulling it of, do a visual check of the hose and replace if there is any form of breakage (however small) you can get the part online but if you can get the same diameter hose from a diy shop etc, that will do fine, keep the old one and use it to gauge the length as the replacement should not be much longer or shorter or it will affect the water level.Give this a go, if you require any further assistance, let me know. Please post a comment if this helps.
