Why is my GE Water Filtration System's operating pressure high?
- R
  rhonda30Aug 16, 2025
  High operating pressure in your GE Water Filtration System can occur due to several reasons. The recycle or concentrate lines might be plugged, which requires disassembling the plumbing to the recycle orifice to remove any foreign particles. The pressure gauge could be inaccurate, needing replacement or calibration. Ensure that the service and CIP valves are not closed simultaneously, verifying that the water path to both is open. A restricted or reduced permeate flow rate can also cause high operating pressure; refer to the causes for low permeate flow rate to resolve this.

What to do if my GE Water Filtration System has low inlet pressure?
- E
  Eric RoweAug 19, 2025
  If your GE Water Filtration System has low inlet pressure, it could be due to insufficient feed water pressure. You can increase the feed pressure, open the inlet/feed valve, and check for any restrictions. Installing a feed water boost pump may also help. Another cause could be a clogged pre-filter, which would require you to replace the pre-filters. Alternatively, the solenoid valve may not be opening, in which case you should clean or replace it, ensure the air line has adequate pressure, and check the regulator for correct operation and setting.

Why does my GE Water Filtration System have low operating pressure?
- M
  Michael ClaytonAug 26, 2025
  Low operating pressure in your GE Water Filtration System can be attributed to several factors. High flow rates may be the cause; try closing the orifice bypass valve and checking the permeate and concentrate flow rates, adjusting if necessary. Excessive permeate flow may indicate improper interconnector installation. Inspect and clean the pump discharge screen if there's low primary pressure. Dirty or fouled membranes can also lead to low final pressure, so clean the membranes. Warm operating conditions can affect pressure, so correct the temperature. If you have a 3-phase power system, the pump might be rotating backwards; switch any two 3-phase leads to the motor starter. Finally, the pump itself may not be operating correctly; refer to the pump instructions for troubleshooting.

What to do if my GE Water Filtration System is not operating after switching it on?
- J
  johnbrayAug 31, 2025
  If your GE Water Filtration System is not operating after being switched on, it could be due to a few reasons. The pressurized storage switch or float switch might have cut power to the machine; check the permeate backpressure or the position of the float in the storage tank. The thermal overload in the motor may have tripped; allow the machine to cool and check the feed water supply and/or amp draw of the motor. Alternatively, there might be no power to the machine; check the fuses or circuit breakers and measure the voltage.

Why is water flowing from my GE Water Filtration System when it's turned off?
- J
  John PeckSep 3, 2025
  If water is flowing from your GE Water Filtration System when it's turned off, the inlet control valve is likely not closing or seating properly. Clean or replace the solenoid valve. Clean the membranes immediately. Water must not pass through the inlet when the machine is off. Repair or replace valve components as necessary.

What causes low concentrate flow rate with normal or high pressure in GE E4-8800?
- D
  Dan FisherSep 6, 2025
  A low concentrate flow rate with normal or higher than normal pressure in GE Water Filtration Systems can be caused by a plugged concentrate valve, requiring you to disassemble and clean the plumbing to the valve. Alternatively, the concentrate outlet line may be restricted; examine the concentrate line for obstructions or a closed valve. An inaccurate flow meter can also give a false reading; check the flow rate manually with a stopwatch and calibrated container, such as a CIP tank.

What causes excessive pressure drop in GE Water Filtration Systems?
- J
  Joseph SimsSep 9, 2025
  Excessive pressure drop (high primary pressure – low final pressure) in GE Water Filtration Systems can be attributed to a few issues. There might be restricted flow after the pump outlet, so check for blockage of the concentrate flow at the inlets and outlets of the membrane housings and at the pump discharge screen. The membrane might be telescoped, covering the membrane housing outlet port; ensure that the anti-telescoping device (ATD) is located properly on the membrane. Severely fouled or dirty membranes can also cause this issue, so clean the membranes.

What causes a Deluxe (DLX) Electrical machine shutdown in GE Water Filtration Systems?
- H
  Hunter CombsSep 12, 2025
  A Deluxe (DLX) Electrical machine shutdown in GE Water Filtration Systems can occur due to several reasons. An alarm condition may have turned off the machine; restart the machine by pushing the alarm bypass and check all possible alarm conditions, including inlet pressure, and push the alarm reset switch. The motor and/or pump may not be operating properly; refer to the pump instructions and contact GE for repair or replacement. A defective or burned-out timer relay can also cause a shutdown; replace the relay. Additionally, the motor starter may be overloaded, causing the heater to trip; turn the switch off and let the heater(s) cool.

What causes low permeate flow rate in GE E4-8800?
- A
  Adam BuckleyNov 21, 2025
  A low permeate flow rate in GE Water Filtration Systems can stem from several causes. It could be due to low operating pressure, in which case you should investigate the causes for low operating pressure. Dirty or fouled membranes can also reduce the flow, requiring you to clean them. If the system is operating on cold water (less than 55 - 60°F or 13 - 16°C), install a hot/cold feed water tempering valve or operate with a feed water temperature of 72 - 77°F (22 - 25°C). Incorrectly installed membranes or a damaged concentrate seal can also be the culprit; ensure membranes are installed in the direction of fluid flow and clean the machine immediately, replacing any membranes with damaged concentrate seals. Finally, an inaccurate flow meter can give a false reading, so check the flow rate m...

What causes declining rejection in GE Water Filtration Systems?
- A
  Amanda HartNov 27, 2025
  Declining rejection, indicated by high permeate conductivity in GE Water Filtration Systems, can be caused by several issues. Dirty or fouled membranes are a common cause, requiring cleaning. A broken or damaged O-ring seal can also lead to this problem; replace the O-ring and inspect the sealing surfaces on the O-ring groove, interconnectors, and end caps, replacing any damaged parts. Changes in incoming water quality can also affect rejection; open the concentrate valve and flush, then test the water for pH, hardness, TDS, and iron content. An inaccurate conductivity monitor or fouled probe can give incorrect readings; calibrate the monitor with a conductivity standard solution or check the readings with another conductivity meter, and replace or clean the probe, checking the connections...
