What to do if my Kärcher Water System pump stops and all lights are blinking?
- J
  John MurrayAug 18, 2025
  If your Kärcher Water System pump stops, and all lights blink, it could be due to a failure on the suction side preventing pressure build-up. Try removing the prefilter and backflow valve, clean them under flowing water, and rinse dirt from the fill neck by opening the discharge. Also, check the suction side connections for leaks. Restart the pump by continuously pressing the - button. Another cause may be the dry run fuse shutting off the appliance due to lack of water flow. Fill the water reservoir and switch the pump on again. Alternatively, the flow meter could be jammed or missing. Check its installation, correct its orientation, and clean it. Restart the pump by continuously pressing the - button.

How to fix a Kärcher Water System pump that runs but doesn't transport water?

  Bonnie TapiaAug 21, 2025
  If the Kärcher Water System pump runs but doesn't transport water, it could be due to air in the pump. Refer to the chapters "Preparation" Diag. A and B and "Operation" for instructions. Alternatively, the suction pipe might be blocked; pull out the mains plug and clean it. Another possibility is a dirty pre-filter; remove the prefilter and backflow valve and clean them under flowing water, then rinse any dirt residues from the fill neck by opening the discharge opening.

Why does my Kärcher Water System pump stop and start, then blink two pairs of lights?
- C
  Courtney JonesAug 23, 2025
  If your Kärcher Water System pump stops intermittently and turns back on, eventually causing two pairs of lights to blink on alternating sides, it could be due to pressure loss from a missing or defective backflow valve. Ensure the backflow valve is correctly inserted into the fill neck, and follow the care instructions. Another cause may be pressure reduction due to leakages in the system. Check all connection locations on the suction and pressure sides, as well as all lids, for tightness. You may also install a pressure compensating hose on the pressure side or a pressure compensating container as a pressure tank.

What does it mean when two pairs of lights blink on my Kärcher Water System pump?
- A
  Allison CarterAug 26, 2025
  If your Kärcher Water System pump stops, and two pairs of lights blink on alternating sides, it indicates a failure in the pressure line with flow being too small, causing frequent on/off switching due to reduced water extraction. Increase the overpump time to reduce the switching frequency. Restart the pump by continuously pressing the - button. It can also be caused by a failure in the pressure line, with the pump frequently switching on and off because of leakage. Check and correct the pressure line for leakages (e.g., a dripping water tap). Restart the pump by continuously pressing the - button.

Why won't my Kärcher Water System pump run or why does it suddenly stop?

  If your Kärcher Water System pump does not run or suddenly stops during operation, the power supply might be interrupted. Check the fuses and electrical connections. Another cause could be the motor protection fuse switching off due to overheating. Pull out the mains plug, let the pump cool down, clean the suction area, and prevent dry running.

Why is my Kärcher Water System pump transporting less water?
- R
  Rebecca GentryAug 30, 2025
  If the Kärcher Water System pump's water transport is reducing or the transported quantity is too low, the suction pipe may be blocked. Pull out the mains plug and clean the suction pipe. The pre-filter could also be dirty; remove the prefilter and the backflow valve and clean them under flowing water, rinsing any dirt residues from the fill neck by opening the discharge opening. Another cause is a leaky suction side; check the entire suction side for leaks. Also, the quantity transported by the pump depends on the transport height and the connected periphery; keep the max. flow height within limits and select a different hose diameter or hose length if necessary.

Why is my Kärcher BPE 4000/45 running but not pumping water?
- N
  Nicholas FerrellSep 2, 2025
  If your Kärcher Water Pump runs but doesn't transport water, it could be due to several reasons. First, there might be air in the pump; refer to the "Preparation" (Diag. A and B) and "Operation" chapters for instructions. Alternatively, the suction pipe could be blocked, in which case you should pull out the mains plug and clean the suction pipe. Finally, a dirty pre-filter might be the culprit; remove it and clean it under flowing water, rinsing out any residual dirt in the filter intake by opening the drain.

Why is my Kärcher BPE 4000/45 Water Pump's water output so low?
- S
  Sean BrooksSep 5, 2025
  If your Kärcher Water Pump's water transport is reduced or the transported quantity is too low, several factors could be responsible. A blocked suction pipe could be the cause; pull out the mains plug and clean the suction pipe. Also, a dirty pre-filter can restrict flow; remove the pre-filter and clean it under flowing water, rinsing any dirt residues from the filter intake by opening the discharge opening. Leaks on the suction side can also reduce performance; check the entire suction side for leaks. Finally, remember that the pump's transport capacity depends on the transport height and connected equipment; keep within the maximum flow height specified in the technical data.

What to do if Kärcher BPE 4000/45 does not run?
- H
  Hannah BarrettSep 7, 2025
  If your Kärcher Water Pump doesn't run or suddenly stops during operation, there are a couple of potential causes. The first thing to check is the power supply; make sure to check the fuses and electrical connections. Another cause might be a dirty pre-filter; in this case, pull out the mains plug, let the pump cool down, and clean the suction area to prevent dry running.

Why does my Kärcher BPE 4000/45 stop and start intermittently?
- K
  Katrina NewmanSep 10, 2025
  If your Kärcher Water Pump stops intermittently and turns back on, eventually showing two pairs of alternating blinking lights, it could be due to a few reasons related to pressure loss. It might be caused by a missing or defective backflow valve; ensure the backflow valve is directly attached to the suction input and check its function and tightness. Another cause could be pressure reduction by leakages in the system; check all connection locations on the suction and pressure sides, as well as all lids, for tightness. Finally, pressure reduction by air in the system might be the problem; consider installing a pressure compensating container on the pressure side or using an elastic pressure hose as a pressure tank.
