You are correct.Also check the tank for lime.By unplugging and removing top of machine (2) screws and remove fill basin.You can then remove your t-stat probe to check.If it is lime up you can crack off the lime and reinstall it in the tank.If limed up I would suggest de-liming.T-stat part# 4314.0001.
Believe it or not I had a customer once that left 6 pounds of butter on top of one of our brewers. They had it cleaned up on the outside so it took me a while to figure out what had happened but I could taste the rancid oils. We ran about 20 pots of just water through it... make sure you let it heat back up before each one. I think the only thing vinegar might help with would be lime/calcium build up so I wouldn't think it helps this particular situation. Good luck!
The metal proble is use to clean out the water tubing. Remove your sprayhead and insert the metal rod up in the hole leaving out about 1-2 inches. Then simply twist and turn the rod about 5-6 times. This will remove any lime deposits. Then flush out with 2-3 decanters of water. You can obtain a new manual by calling customer service or going to the website-www.bunn.com going to @home, then products-click on your brewer-and then select use and care manual and you can print it out or view it online.
I always use CLR to clean my coffee maker. You don't need much more than 1/4 cup and mix with 8 cups of water and brew it like you would make a pot of coffee, then dump it out and run 2-3 more pots of just water, that should work fine. Also, run vinegar thru the machine once in awhile to help keep it clean
You will need the de-liming tool to proceed. Run a pot of white distilled viniger thouth the coffe maker. Viniger is a excellent cleaner & will not hurt any internal parts.
Hello this coffee maker has a one and a half gallon internal tank, could be one of a few problems, first thing to check is the spray head, unscrew this you may need some channel locks to get it off and check it..use a tooth pick to clear the 6 holes with any lime that may have formed...also if you use a commercial coffee company for your coffee they should have supplied you with a spring to clean the spray head tube.
After checking these 2 items the next thing to check is there enough water in the tank..when the vpr is left on and not used for a few days the water in the tank evaporates..it takes approx two and a half pots of water to fill up the internal tank...try pouring another pot of water in...also turn machine off and take the 2 screws out of the top and see if there is lime blocking the drain hole in the fill pan.
Hope this helps...please feel free to comment again if you have any other questions...Good Luck!!! Mike
Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.
