I was checking the pressure on my classic yesterday and after a minute or so the flow stopped completely. It turned out to be a blocked solenoid. This is what I did to check and remove it for cleaning.

1. Check that water flows from the OPV return pipe back into the reservoir.

2. Remove the black hose which comes from the solenoid to the outlet pipe, I used pliers on the hose clip

3. Use a 13mm socket to take the top nut off then lift the black magnet off

4. Remove the two allen bolts with a 4mm key

5. With the solenoid out you can undo the 14mm nut and disassemble

I forgot to take pictures of the solenoid out but there are two holes with rubber o rings, if you blow through it and block off one hole then the other you can check which one is scaled up.
I left mine in de scaler overnight then cleaned it out with a pin and a match.

Reassemble in reverse and it should be working again.
