My machine wont drain or spin. if i maually empty, it will eventually start a wool wash but then says error e20 but filter is clean and no kinks or blockage in drain pipe. should i replace outlet pump?

Do the following.

1. Switch off the machine, unplug or disconnect the mains AC power to the machine and turn off the water supply to the machine.
2. Remove the filter access panel.
3. Remove the filter and make sure that the filter is not blocked and is clean and clear of all debris. Clean as required. Note that depending on the machine type you may get a lot of water coming out of the filter when you remove it if the machine has not drained successfully. Note that if the machine has stopped and not fully drained then you may be able to drain out the excess water by removing or disconnecting the waste hose and laying it on the ground in a tray. It may take a few minutes to empty but it will save a small flood.
4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked.
5. Also check that the main waste drain pipe, if you use one, is not blocked and clean if required.
6. Reconnect the power and switch the machine on.
If the problem persists then do the following.
7. Switch off the machine and disconnect the mains power.
8. Check the electrical connections at the pump and make sure it is operational.
9. Remove the connecting hoses, and expect water to drain out and make sure the pipes are not blocked with debris or any object blockage.
10. Makes sure the pump appears clear and that the impeller looks in good condition.
11. Reconnect the hoses and then reconnect power and switch the machine on.
12. If problem has not been corrected, then remove the pump and check that the drive coupling to the motor is OK and that the motor turns OK. If all is well then replace the pump.
