the fuses relevant to the wipe/wash system are fuse 43, 39 ad 48
I have checked fuse Nos 39 and 48 and they are both serviceable. Fuse 48 is the rear wiper (proved by removing it. Fuse 43 is not fitted and is shown as the headlamp washer.
On my distribution diagram, the only other picture of a washer is through fuse 63 which also serves the windscreen demisting fan. The fuse is serviceable and the fan works but the washer does not.
Therefore, I can only conclude that the Windscreen wash pump ran dry because of sediment in the tank and the pump burned out. I won't quibble, you've earned your £15 but I can't rate the result as satisfactory. good luck.

I am sorry that your pump may be faulty but this is beyond my control and is in fact not related to the question that was asked if you read the question as posted.
I answered the question that you asked about fuse numbers.
The rating is for MY SERVICE, which as you said, has earned the payment. You have rated the outcome of your issue, which was not in scope for the question, and is out of my control. This low rating in fact punishes me.
