Maxx 470 water pressure problem

**Mr. Slide** · 11-24-2009, 04:42 AM

Water Pressure starts out of the wand good for about 15 sec. then go's to a drip, without the gauge dropping at all, then increase back after about 45 sec. and may do that a couple of times, then seems to run fine???

HELP

Thanks, AL

It could be something as simple as a worn disconnect not engaging all the way and not opening the little shutoff cone.

I agree with Kevin. There should also be an outlet check valve located somewhere toward the front of the machine; that could be clogged as well.

Have you descaled in a while? That might be worth a shot.

I have 2 new heat exchangers.
