Help please! My son's Roomster has just lost part of its rear washer; water is still pumping out but not spraying. Looking at spare parts online... I'm wondering if part of the original mechanism (the stem?) is still stuck in there? Any advice welcome, don't want to start fiddling and make it worse!

Thank you.

Hi, i had the self same issue. Missing is a small cap that diverts the water onto the screen. You can get replacement caps but they did not fit my model .

The ultimate solution for me was to get a complete wiper arm. The difficulty is removing the current wiper. I ended up using a puller to get the broken wiper off. Then it was a simple swap. The replacement wiper arm was about £15..

Many thanks Mikescar, that's reassuring - it does seem tough to get off but I'll persist... appreciate your advice.

This is the puller i used...
