No hot water, but dishno hot water, but dishwasher has hot water, whywasher has hot water, why?

Your question is a bit vague but if I understand it correctly, you have hot water in dishwasher and NO hot water in sink. Correct ?

There are 2 scenarios:
1. Dishwasher has separate water valve from sink supplies. Sink hot water valve is either closed or it is clogged with debris.

2. Some dishwashers - especially those used in Europe - are connected to COLD water and heat its own water inside the dishwashers. That's why you have HOT water inside Dishwasher and no hot water in kitchen sink and/or in rest of the house.

Hope that explains. Back to you. Milo

More details please! You have hot water to the DW but not the kitchen sink, Correct? Does the sink have cold water? If it does then I'd suspect the hot water ports on the cartridge are blocked. Shut the water off to the faucet and open it up. Check and clean the inlet ports on the cartridge. Now place a pan over the open faucet and turn the water back on for a minute to flush everything out. Reassemble and test. If that doesn't get it click back and tell me about it. B Good luck, Tom
