2023 HS washer fuse

[plodder]

Hi

I have lost wiper washers

Initially rear, could hear noise but no water

Now no noise at all and no front water either

Fuse?

Unsure which

Thanks in advance!

At the risk of stating the obvious have you checked the fluid level first?

Firstly is it safe to assume that the wash jet water reservoir is full of course ?.
If so, it is very likely that it will be the same washer motor and reservoir that is used to supply pumped water for both front and back screens.
For easy access the reservoir is usually located under the bonnet.
When the fluid is allowed to drop too low, it is normal for the rear jet to stop spraying first, due to the distance the water has to be pumped, then followed by the fronts jets.
If the washer jet fluid IS too low and there is continued use of the washers, this can cause the pumping section of the motor to fail.
This can happen because it relies on the water to keep the pumping mechanism cool and not then in turn overheat the motor.
If it does over heat, it could blow the protection fuse I guess.
Maybe check the handbook to see if the washer jet pump has its own dedicated fuse.
If the fuse has blown and it is then replaced, can you now hear the washer motor operating again ?.
If you have motor sound but no water coming from the jets, then I suspect the pumping section has failed.
If you have no motor sound then it could be the motor of the pump that had failed.

It’s a know thing on the HS that a pipe comes off by the bulkhead up by the brake servo and you have no water to the rear if you keep trying and run the tank dry you may have damage the motor pump as well.
