Notes:
- Please note that for this part to hiss indicates another problem:
- You may have limescale build up in this valve, and the machine needs to be descaled prior to changing this part
- Your boiler pressure may be exceeding 1.5 bar, and this is a failure of the pressure regulator/pressurestat either from limescale buildup
- If water is spewing out while the pump is running at the same time, then the water is too pure and the sensor can not send 5 volts of water through the too pure water. You may need to change the water, or again, the sensor may be completely limescaled.
