The pot is leaking water. We tried putting a new gasket on it (make your own from Lowes) but it did not solve the problem.

The A10 has a semi-sealed tank that keeps +1 pot of water heated and ready to brew. Pouring in a full pot of cold water will fill the top tray and allow a slow trickle of cold water into the top which forces hot water to over flow into the brew basket. This continues until all the cold water drains into the heater tank. So the brew is matched volume per volume. UNLESS the tank was empty or not filled prior to brewing. Follow the brewing instructions from Bunn (on line for *FREE* download at Bunn.com)
* If it leaks (from the bottom) only when you pour in water. Then your pouring it too fast and over flowing the fill tray. slowdown, watch the level in the tray. do not fill past the lid.
* If it leaks just sitting (not brewing) then there is a hole in the tank. Call for service.
* If it leaks after filling the tray half way. then the top of the tank has a leak, loose, cracked, or missing gasket. There is quite a few gaskets on the lid. Call for service.
* Final; Leaks are always bad around electrical equip. Best to unplug and call for service to be safe.

PS. Check your using the correct size decanter for this brewer. If it's a 10 cup brewer then make sure all the decanters in the office is also 10 cup. Pouring a 12 cup pot into brewer will have 12 cups of coffee come out (over flowing the 10 cup pot.) Note that not all decanters are made the same size. Other brands may be different. Test by filling a pot with water (from faucet) then pouring directly into pot in question. It should match and not under fill nor over fill.

If a new gasket didn't solve your problem then you will need to search for a crack in the plastic either in the gasket seating groove or the diffuser that rides atop the gasket. Whether it is fixable or not will depend on what is cracked. The diffuser can be replaced...the groove can not. A new top-mount valve is about $100.

If this is between two screws when your looking at the front of the pump then it is in the suction gasket between the pump pot and the pump housing and the one you have could be a paper gasket and should be replaced with a rubber or cork one this can be done by removeing all four screws and gently pulling the two pices away from each other and clearing the old one out and putting the new one in. That is the hard part as there will be a extention comeing from the pump into the pot and is about two inches long you need to clear this with the new gasket and then just put the screws back in and fill with water.
If your looking from the back of the pump and the leak is between the motor and seal plate of pump then it has a bad seal and will need to be replaced. For this you seperate the half's of the pump by takeing the band clamp off pulling the front from the back then remove the five screws on the defuser pull it off if there is a screw in the center of the impeller, that is left handed and unscrews by turning clockwise. then unscrew the impeller and replace the seal. Reassemble pump with new "O" rings and fill with water.

Difficult to get to but not complicated to replace. Remove housing bolts, clean the surface, (engine side) then put on new one with gasket if applicable. Tighten botlts in sequence slightly so as not to warp new waterpump...they are made of cast aluminum, (pot metal), and if you individually tighten, you run the risk of warpage and developing a leak. This is an easy fix...but in a tight spot.

Check the gasket. Sounds like you have a leak somewhere causing the ice formations on the bottom. Easy way to check this is to have a steamer or a small pot of boiling water (steaming hot) while the frezzer is runing hold the pot of steaming water and watch the steam. You will see the steam going into the frezzer. BINGO leaking gasket. May need to replace the gasket or may beable to fix. You will see and know what to do. Keep me posted. Good luck.

I obtained Bunn washer seal repair kit from buy-it-now-store.com for $6 plus $7 S&H and it solved the problem.

try aviation gasket maker / messy but stops leaks .make sure you have all surfaces clean no debris stuck on them and the right thermostat that fits and the proper gaskets or o ring and a little avaition gasket glue should cure the problem . leaks require patience :) gl

Had a little problem loosening the nut from the heating element, but once I got it off, cleaned all parts , went to an auto supply store and was lucky to find the right size gasket ( it was a part for a Nissan auto ) , used Permatex silicone gasket sealer, put all parts together, tightened the nut real tight, made all electrical connections, tested the pot with water, heated up real fine , no leaks , Problem solved.

If your dishwasher leaks, check these:Main tub seal
Door gasket or seal
Water-inlet valve
Hoses

Main tub seal
Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

1. Lower rack
2. Spray arm
3. Spray arm support
4. Wash/drain impellers


Then pry the seal out of its housing and replace it.


Door gasket or seal
Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. 


Water-inlet valve
The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses
Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.
