Hi All. I have a Logik liw814w15, bought in 2017.
Yesterday, half way through a cycle, it stopped working and showed error code E21. This is apparently a problem with pump drainage..
I have done all of the following:
- I have taken the filter out and cleaned it
- I have taken the pump out from underneath, disconnecting all the pipes and cleaned them (not much residue there)
- I have taken the pump apart and cleaned inside (not much residue there either, moves freely)
- I have blown into the waste pipe, it is clear.
Tried again and still showing the same error message.
Any ideas what I can do next??

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Logik LIW814W15 showing E21 mid-cycle after drainage path cleaned
- The problem
- A Logik LIW814W15 stopped halfway through a wash cycle and displayed error code E21, described in the thread as a pump drainage fault. The owner had already cleaned the filter, removed and cleaned the pump and connected hoses, checked the pump moved freely, and confirmed the waste pipe was clear, but the fault remained.
- Likely cause
- If the machine is pumping water away normally, the accepted reply says the fault is more likely to be in the pressure system or a blockage affecting that system rather than the drain pump itself. If water is not draining fully, a remaining blockage in the drain hose end or the sink waste connection was considered more likely.
- What fixed it
- The accepted advice was to first confirm whether the machine is actually draining correctly. If it is draining, focus on the pressure system rather than the pump blockage already checked. If it is not draining fully, recheck for a missed blockage, especially at the end of the drain hose and the sink u-bend/spout connection. No completed repair was confirmed in the discussion.
- Checks to try
- Cleaned filter
- Removed and cleaned pump and connected pipes
- Pump checked internally and found to move freely
- Waste pipe blown through and found clear
- Advised to confirm whether water is actually pumping away
- Advised to check the end of the drain hose and the sink waste spout/u-bend connection
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

The first thing to establish is - is the error code accurate? In other words is there a problem with drainage? Is the water being pumped away OK or not? There's no point looking for a problem if it doesn't exist. So with an error code implicating a problem with draining the water if the water is being pumped away OK then don't look for a blockage. Washing machines receive the signal that water has emptied out ok from the pressure system, which can be faulty or suffer a blockage. So if water is being pumped away OK but the error says it isn't the problem is likely to be with the pressure system.
If the water is actually not draining fully then there must be a blockage you haven't found. If it pumps into the u-bend under the sink remove the drain hose and check in the end of the drain hose and the spout it pumps in to.
