Bosch WAE28220
After washing, the centrifuge and the done lights keep blinking, which is an indication that the filter is dirty. I looked on the bottom and the filter is NOT stuck. There was nothing in it and could turn freely. Next to the filter there is this small hose that can be used to let out water before opening the filter. This small hose has NO water in it. When I open it nothing comes out. Any tips on how to unclog that part?

Bosch WAE28220 flashing spin and end lights after wash
- The problem
- On a Bosch WAE28220 washing machine, the spin/centrifuge and done/end lights were flashing after a wash. The owner believed this indicated a dirty filter, but the pump filter was free to turn and had no debris. The small drain-off hose beside the filter was empty, with no water released when opened.
- Likely cause
- Most strongly supported diagnosis was a draining fault not necessarily caused by the filter itself. Suggested causes were a blockage in the main drain hose, sink spigot, pump housing or sump hose, or a weak/failing drain pump. The empty small hose was described as not necessarily faulty and may simply have had no water in the sump at that time.
- What fixed it
- Recommended action was to isolate the machine from the mains, then check whether it actually drains on a rinse and spin cycle, inspect the main drain hose and sink plumbing for blockage or kinks, inspect the pump housing and impeller for debris or damage, and check the sump hose for trapped items. If the pump only hummed, was noisy or drained weakly, the pump was suggested as a possible fault. No completed repair was confirmed in the discussion.
- Checks to try
- Pump filter checked and found clear/not stuck
- Small emergency drain hose checked and found empty
- Advised to run a rinse and spin to confirm draining
- Advised to inspect main drain hose for kinks or blockage
- Advised to inspect sink spigot if fitted
- Advised to inspect pump housing and impeller
- Advised to inspect sump hose between tub and pump
- Parts or tools mentioned
- Torch
Safety: Isolate the washing machine from the mains before checking internal parts. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If the “spin/centrifuge” and “done/end” lights are flashing together, it often means the machine thinks it has a draining problem, but it does not always mean the pump filter itself is blocked. If the little drain hose is empty, that usually just means there is no water left sitting in the sump at that moment.
Before checking anything internal, isolate the washing machine from the mains.
1. Check whether it is actually draining Run a rinse and spin. Listen near the pump area at the bottom front. If you can hear the pump running but little or no water reaches the standpipe, there may be a blockage further along rather than in the filter.
2. Check the drain hose and sink plumbing Pull the appliance out and inspect the main drain hose for kinks, crushing or a blockage. If it drains into a sink spigot, remove the hose and check the spigot itself is not clogged.
3. Check inside the pump housing With the filter removed, look inside with a torch. Check for debris around the pump impeller. It should turn with slight resistance, not be jammed or floppy/broken.
4. Check the sump hose A common blockage is in the large hose between the drum tub and the pump, where coins, grips or fabric collect. This needs access from below or the rear depending on version.
5. Consider the pump itself If the pump hums, is noisy, or drains weakly, the pump may be failing even if the filter is clear.
The small emergency hose does not usually “clog” separately very often; it is only a drain-off tube from the same sump area. If you are not confident opening hoses or checking live drain operation, it is best to get a qualified appliance engineer. Any mains electrical work should be left to a qualified person.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
