The first step is to make sure the pump is fully disconnected from the plug socket. then we need to remove the 8 screws around the middle of the pump like shown in the image which are around 1/4 of the way up the pump there is 2 screws on each side that need to be removed.

Once these have been removed you can then lift the lid but please do this carefully as there is a wire connecting the control panel to the control board so please disconnect this which is very easy to do by pressing the little clip on the connector and pulling the 2 wires apart as shown in the 1st photo below.

The Next step is to remove the 3 screws shown above in the 2 centre photos (PICTURES 2 AND 3) which is the control board cover. once these are removed next remove the 2 screws that are securing the main power cable strap shown in the last photo ( picture 4). then after this you will need to loosen the power cable marked C1 & C2 on the control panel board this will give you enough room to access the water pump but if you want you can also unscrew the earth cable from the heater block which will allow you to totally remove the bottom of the casing but this isn't required to resolve the E02 error (and the less you take apart the less you have to put back together.
