25-pah issues.

Have you checked the latches and seal on the hopper? Some have found this effects their burns. Dollar bill is the test I've heard of.

Have you changed pellets? Using older ones?

Edit: Lots of fines in the pellets?

Do you have a OAK on your stove and if so is it open on the outside as in not covered by snow?

Try fluffing your gaskets up some by squeezing them with pliers. The dirty burn is an air mixture issue but not sure what issue you can be having. It could be that you have hit some sib-par pellets within the lot you have too. Anything is possible.

I know you said you've cleaned but are you doing the banging thing like many with your stove do? I shoot my stove in spots before and after a clean. The ash build up can insulate temps more than you think. Are you running the 6-4-1 like many ESW people do? I am not real familiar with your stove since I run Harmans.

Have you used the search bar here and plugged in your issue for research? I have seen this problem many times. Good Luck.

Good point Bkins...

Some have found the hopper not seating on the gasket well due to slight warpage on lid - Did you do dollar test on the hopper too? It is part of the system under vacuum... Double checked ash clean-outs to make sure they are secure. Cleaned combustion blower including windings (blow them out with compressed air)? Lubricated with electric motor oil if needed? New gasket on exhaust blower? Checked the seal on the auger?

Could just be a change in feed stock on the pellets... don't always get the same from batch to batch Might want to try something different just to rule it out...

I use a pet hair grooming brush myself. 'Fluffs' them up real nice and quick.

Are there some other hidden areas that can be jacked up and haven't been cleaned since you ran the ashy pellets? Some of these stoves seem to have some hidden areas often overlooked on the cleans. Not sure about yours. I have seen some complaints on ESW stoves needing a new door gasket when they were fairly new also.

There are quite a few PAH's owners here so hopefully one will chime in with a magical answer soon.

I also have the 25 Pah stove we bought new in September 2014. We've had a lot of trouble with black soot on the glass usually within 15 minutes of ignition. This has been a problem since the first time we fired the stove. First off the bottom numbers on this stove come preset at 1-4-1. I really don't mess with them as I figure England knows where their product performs the best. We have installed a new blower motor, & control board and new gasket around the ash pan. (Warranty covered motor & control board). Since installing the board & gasket we don't have the overflowing burn pot, we still have some soot. But we r finally getting flyash so that's some improvement. Still not sure we get much heat from the stove, like I hear from others. It's 45 outside, 67 * 7 ft from the stove in a well insulated but open room. We are still deciding if we are going to keep this stove or return it. The store knows all the problems we've had as well as England stove works. Good luck. Check out the ash pan gasket. We recently found this problem and glued a new one over top the old because it's a pretty thin strip.

If it's good and clean, including the heat exchanger, then you've got an airleak or a blockage somewhere. It sounds like you've got the clean-out technique down good, banging on the wall of the heat exchanger until nothing more falls out. That's usually a LOT of banging, at least on my stove. You wanna check all the gaskets, door, glass, ashpan, hopper. Less likely leaks would be the exhaust blower gasket, cradle gasket, and potential sealing issues of the burn pot - warped flange or something stuck on the sealing edge of either the burnpot or cradle. You can bump up the Low Base Air, but if it ran fine before you're just band-aiding things. You might wanna reclean that heat exchanger if you've run it sooty much, it doesn't take much to inhibit the flow through there and hurt the airflow.

Looks like I got it. Once I got home I grabbed my rubber mallet and gave it some wacks with it and sure enough a good amount fell down into the clean outs. I always tapped it but the mallet did the trick.going on four hours and the glass is still clean as can be. Thanks for the help everyone.

There ya go! I know I have to be fairly vigorous with a wooden mallet, and I don't quit until nothing more will fall. That can take quite a while, I just keep moving around, side to side, top to bottom. Glad it's working good again!
