Mine stopped working back in May, whilst it’s not the question you are asking, I swapped the connectors on the rear and front pumps to prove the wiring was good… ie the front screen wash stalk position then operated the rear wash, so I knew front connector had power… rear then did nothing, so I knew it was the front washer pump that had failed. Got one from the bay of e for like £12 I think. Swapped out and all still good.

The front and rear pumps are the same so you can swap them over in the meantime so at least you can get windscreen washers going again. The plastic water pipe connectors are just a push fit, so you might need to cut half inch off it to get a good water seal on the new pump as the existing end can stay flared out when you pull it off, if that makes sense.
