Clean a Bunn coffee maker once every three months if you have hard water. ... Unplug the Bunn coffee maker from its power source.

I used silicone to make my own gasket, worked perfect

This could be an issue with the wiring of the fill and brew valves or it could be an issue with the control board. When you draw water off, the machine should replace the same volume of water by opening the fill valve. If the brew valve is opening at the same time, tgen there is an issue. I recommend placing a service call.

* Bunn model # for specific solutions. * Most Pro/Office models have a pre-heated tank. * Most models (Without Vacation or heater switch) will be heated all the time. * Care must be taken to keep the inner tank filled. * Pour cold water into fill tray till water comes out of the brew basket. * Water will stop coming out of brewer once the tank has been topped off. * If pot is not able to brew after 20 mins of pre-heating. Then call for service. * Note; most office and Pro machines used in food establishments are from coffee vendors. The larger machines should be serviced by qualified Bunn service techs. * Contact your coffee vendor or Bunn service ctr for advice. Aloha, ukeboy57

Bunn, DUAL brewers are large volume (1-1/2 gal per thermal Dispencer.) In most commercial VAN operations there is a requirement to cook and assemble food in a sanitary food approved kitchen or process plant. Brewing would be done at the kitchen. To use this type of brewer would be to get enough 1-1/2 gal servers to cover your needs for the event. Brew everything you need in the morning and just take the servers to the event. I remember waking up at 4 AM to brew 25 servers for big events. We even did a mid morning run with another 15 servers. You can also install low wattage warmers designed for the servers. I suggest two warmers to keep regular and de-cafe hot. The rest can be set aside. Some servers will stay hot enough for up to 4 hours. * Installing the brewer in the van has problems with keeping the water level. You will need a "Boat kit" to allow for sloshing water. You also need a pressurized water tap. Power is rated at 220-240 30 amps. (40 amps if your at 200VAC) * Check with your local coffee vendor for advice. Aloha, ukeboy57
