found it from Tara put online in nov 2008 Thanks this is it
Had the same problem... although I don't have particularly hard water, the heater block corroded just enough to stop most of the flow after about 4 years. Disassemble the handle to get at the heater block (3 pairs of screws/bolts), remove the tubes with needle nose pliers, use a paper clip to knock out the corrosion on the front tube on the heater block, flush with a syringe to get rid of any other bits of corrosion (some extra plastic tubing connected to the back tube of the heater block helps here, and catch the water from the front tube to prevent water in the electronics...), reassemble (avoid disconnecting any wires...) and try it out. Worked for me! I REALLY have to thank the person who suggested this fix! THANKS!!!
I used regular pliers , phillips screwdriver , the pointed end of a compass and a turkey baster full of water to blast it out . You have to improvise . Take your time watch the little rubbers on the heater make sure its not hot . It was just the inlet gets pluged up in the heater . You have to take off the tools then its the bottom set of plastic not the handle . You can test by pushing the plunger at the top . You must take the handle off . Loosen the pieces it just came off for me then snaps back on . This is all it was for me , very simple . I am disabled and did it on a extra old carpet a little at a time over a few hours . For someone healthy its a hour job tops or less . Just be patient . God helps those who help themeslves and asks for patience .
I would do this on anyone with a pass through heating element . It fixed mine the clamps are squeeze types . If its really pluged just find a tube or washer tee and modify to bypass the heater just dont throw the heat switch or take off the leads / seperate and tape them up . But a shot of compressed air should do the trick for a bad one .
