"Andrew"
Andrew - f10 fault is from the fire being snuffed after the burner is lit. So in other words the boiler lit fine and then after a short time just went out. This is usually caused by water build up inside the heat exchanger. Did anyone flush the drain lines. If the boiler doesn't drain properly you will get F10'S. I suggest that you go back and read what I and others have written on this site.

"Munchkin problems"
We purchased our house in 2007 and was initially impressed with the Munchkin. We've always had problems with the f09 error; I figured out how to take care of that problem. Now it's f10. I live in a small town where there are only a four people who know how to work on it. The first guy came out and did all the maintenance, $250. That night we still had f10 problems. He admitted he didn't know what to do and gave us a name of another business. That guy came out, said he fixed it, and gave me all the history on Munchkins and boilers, $250. Within an hour after he left, f10. I understand that there may be condensation. I have the third business coming out today.

"Blower Racket"
J. C. Pernicka--Bellvue, Colorado---Yes, I can tell you from 40 years of experience: Installation is a big deal, especially with the new high efficiency boilers. If you have a Dungs gas valve look at the swirl plate and make sure it is not disintegrating, especially since you have replaced blowers before. It is a plastic plate between the gas valve and the blower that swirls the air and gas. If you have a Honeywell gas valve, make sure that you didn't suck something into the blower. Something may be unbalancing the impeller or the bearings maybe going. Lastly, you need to have a combustion analysis on the boiler. You may mistakenly believe that the blower is making the noise when it is "flashing" in the heat exchanger caused by the boiler pump not moving water through the hx fast enough. If so, clean the pump and or replace the cartridge. Munchkin is a good boiler and trouble free if installed correctly and maintained. (You do maintain the boiler and clean the combustion chamber?)--read the posts--

"Great system!"
The unit has been great. Maintenance free since it was installed except for cleaning. upgraded it with an outdoor temperature sensor last year. Would put another one in without a hesitation. Would definitely use a different contractor though, American Services in nw Colorado won't get any more of my business!

"Working 7 years and still going strong..."
I had our Munchkin t50 installed in 2005. The installer was a real pro and did a great job...kept inlet and exhaust vents far apart so the intake fan/blower doesn't pull in the acidic exhaust and fail, very clean and professional job (some other plumbers and contractors have commented on the good design and quality fittings/components he used). Initially we used the same installer for cleanings but it cost too much so I changed to another heating company and I have them come every other year to clean the leads and heat exchanger...they tell me it is pretty clean so I think it may not be necessary for annual cleanings in my case. The system works fine so far...provides adequate hot water (we also have a SuperStor Ultra 45 Gal HW heater for a family of 7...1900 sq ft home) and heat. Haven't had a component fail in 7 years...seems from one reviewer that installing these correctly and with adequate sizing/cleaning is critical...not to mention an honest installer.

"Unreliable Junk"
Purchased house 7 years ago and was impressed with the presents of the Munchkin boiler and a very well done installation. So much for looks. The plastic impeller of the blower failed within 2 months the first time and continued to disintegrate (had four replaced with the same type that continued to fail). After the first one failed, redid the vent (although the original installation was done exactly per the manufactures specification) so that under no circumstances could the exhaust feed back into the air intake. Plastic continued to fail. It's always interesting to hear "the problem is the installation" when dealing with a poorly engineered component. Finally, after 4 years of continued problems associated with the design, I called http directly (it also helped when I informed them I run a military failure analysis lab) and they sent me a new blower with a metal impeller which has continued to operate for 2 years without falling apart. However, now we have a sever vibration when the blower clears the boiler just prior to ignition, that is if it starts. We can not leave our home in the winter for any period longer than 24 hours, since we never know when or if the boiler will operate. And, yes, we have had all the service calls recommended (averaging 4 per year) by factor authorized repair companies and have spent about twice the cost of the unit on labor. I would have been money ahead to pitch the unit and replace it with something "more reliable"?

"Banging in Boiler"
Finally! - Some people who know these systems....I Bought an 80m in 2007, and have pretty good luck with it so far. I have a 2 zone system with dhw heating as well. Recently, the system has started banging shortly after the dhw cycle starts. My plumber said that the water is "flashing" in the boiler. The temperature shoots up very quickly and the burner modulates down and will eventlally shut off. Now, I'm not a hvac tech, but it seems that this would happen because the boiler is not getting enough water flow. Sure enough, I read on one post about how a bad pump could cause this. My question was I was wondering if anything else would cause it. Are there any tests that will narrow down the problem - thanks!!!

"No Code--No Lite"
Diana--Cheyenne W---Well, first read the posts. Sorry that you had so much trouble. You have a gas reversion problem because of faulty exhaust and intake installation. When did you do a major cleaning and tune-up? No Code--No Lite: No code tells me that the major components are ok. No lite tells me the following: No gas(propane tank empty or valve off?), no spark or hot surface ignitor not functioning, no combustion air. Those are the three things necessary for combustion. Check to see if you have gas. Check to see if you have spark or that the hot surface ignitor is bright red. Is the spark cable grounding out? Is the spark probe cracked and grounding out? This is what I think it is. You have a plugged condensate drain and the moisture in the combustion chamber is grounding out the spark. But I think that you would still get a code. Keypad plugged into the control board? Hope this helps.

"Not liking Munchkin right now"
We have a Munchkin boiler for heating our home and our water. First the fan caused problems - had at least 3 new fans before we finally had one that did not separate. Have had a new circuit board installed, then it worked well for several years. Now while we were out of town, something went wrong. Came home to hear the boiler trying to light, however it did not light. No code to determine what may be the problem. Our local plumbing company had been helpful - not so much this time. They cannot determine the problem and aren't very communicative with us. Ordered and installed a new circuit board and that did not fix the problem - so we have been without hot water and heat for the past two weeks. We live in an area where the lows have been in the 30'S. Snowed this past weekend - so we really need to either solve the problem or install a new boiler.

"Mr"
Do yourself a favor and do not buy any Munchkin products. My boiler is totally junk and needs to be replaced after only ten years of use.
