My tub/shower went from having normal hot water pressure to almost NO hot water. It trickles out of the tub faucet and barely comes out of the shower head. I have a Kohler Forte model single faucet. I've read that I should remove the handle plate and clean any debris, but I don't know how to get the plate off. Is this what I should do and, if so, how do I do it? Thanks for the help.

Shut off supply lines first. Here is the installation manual for your unit, page 9 or so should show how to service the cartrdige. http://www.us.kohler.com/onlinecatalog/pdf/1103747_2.pdf Once you have the cartidge out tightly hold a towel over the opening for the cartridge and turn the supply lines back on for a few moments to flush line debris. Carfully inspect the inlet port on the cartridges hot side, debris hides there.

It looks like the manual is for a sink faucet. My problem is with the hot water pressure in my tub and shower. Can you help me? Don't know how to get the plate off. Thx.

Go to this ite and scroll down until you find your tub valve. You should be able to get the manual once you find your valve. I just grabbed the first one I saw but tubs are lower on the list.
