You could always wash the dishes in the bath. Or you could change the diaphragm in the diverter valve. Download a manual from Grant website if you haven't got one. (Manual that is, not website).

You want help for no cost. I told you to download the manual, where you would have enough information to make sense of replies. I assume you haven't got a manual yet.
If it's not your trade, and you know nothing about it, either get someone whose trade it is, or be a bit less demanding.

sorry mr oilman.....point taken...i have a manual now!
Section 9 deals with replacement of componenets, and with a bit of luck, 9.3 is how to replace the diaphragm.
To check correct operation, remove the microswitch assembly fro the front of the valve, and then turn the hot water on at a tap, the pin on the valve should extend to 11mm.

Well I expect it's fixed anyway. The OP raised the query in June 2008. Try to keep up.
