No hot water in bathroom faucet.

[Cooperhawk]

Our 2012 Journey has hot water to the shower but no hot water to the sink. I turn on the hot water valve and cold water flows and after maybe 3 or 4 minutes it might turn luke warm, but that's all.
The DWs make up sink and vanity has hot water with no problem.
Help!

This sounds like an easy fix. Many times through hooking up the hose, sandy grit gets introduced into your water system. Our coaches have strainers and such to reduce the amount of grit that gets in, but sometimes it does anyway. It is probably the strainer on your faucet on the hot side that is partially restricted and not allowing hot water to pass through. Simply pull the hot water dip tube from underneath the sink and inspect for deposits that block the flow of water. Obviously, confirm that your water supply is turned off and that the pressure has been expelled....on both hot and cold lines....before disconnecting the tube connector underneath your sink. I can almost guarantee this will be the problem. But if it's clear, then your sink fixture would need to be replaced. No need to order an RV specific fixture. Go to your local home center and pick one out that you like.....as long as it's 4" on center. Hope this helps!

Well it would seem then there wouldn't be good water flow, but there is. I will check that however.

I would agree with you if speaking of the aerator at the faucet as the cold and hot both flow through the same part! Not sure of what other filter would be in the line to effect only the hot water.
My thought would be that the cartridge inside the faucet is at fault. Assuming the faucet is as built and not changed at some point?

Click these snips for what I see as the problem!
Still looks like this faucet?

The part numbers if shopping at any big box store? This is assuming they have not done something like change model numbers, etc., so approach with care!!
I never trust until it works!

A part blowup to see what I think has happened.


Way down in the faucet there is a cartridge of metal and plastic. The metal handle is poured/made in the plastic of the cartridge ball. Normally the metal move forward/back to turn water on. But it has to turn left/ right to choose hot or cold. The metal can break loose from the plastic in a way that lets it still move to on or off. But it can be loose to turn the metal and not move the plastic. So I think you are stuck with the plastic part that moves from cold flow to hot flow being left with just a tiny mix of hot in a lot of cold and moving the handle doesn't move the plastic!

Kind of guessing but a look at a store on the cartridge may let it make more sense!
I numbered the steps but getting some of it to break loose can takes some fuss as the minerals tend to stick them together! A little fuss and hold your mouth just right, may help??

Not usually hard but just fussy at times. Do Turn off the water FIRST!

Link to new design cartridge which looks like it might be less plastic and last better? Also some videos that may make it more clear than "word salads"!
