  If your purway Crystal Group Water Filtration System isn't producing pure water despite the pump working, it could be due to several reasons. The inlet water solenoid valve might be defective and need replacement. A pre-filter could be blocked, so check both the pure water and wastewater and replace the filter if necessary. The check valve might be blocked and require replacement. The reverse osmosis membrane could be blocked, requiring cleaning or replacement. Finally, the wastewater valve might be open without authorization, in which case it should be replaced.

  If your purway Crystal Group Water Filtration System is producing very little or no pure water, several factors could be responsible. It could be due to a blocked pre-filter, which requires replacement. The reverse osmosis membrane might be blocked, needing cleaning or replacement. The inlet solenoid valve might not be closing or opening, and would need replacement in either case. The check valve may not be closing, requiring its replacement. The booster pump might not have enough pressure, so measure the water pressure of the pump and replace it if necessary. The wastewater valve may not be closing, and would need to be replaced. Lastly, the device could be losing water pressure, so check for leaks.

  If your purway Crystal Group Water Filtration System's pump won't switch off, it could be due to a defective high-pressure switch. To resolve this, pull out the mains plug and replace the high-pressure switch. Another cause could be a wet connection terminal on the control unit. In this case, pull out the mains plug, pull out the connection strip, and dry it. Lastly, the electrical line to the high-pressure switch might be interrupted; pull out the power plug and reconnect the electrical line.
