Solenoid, inlet solenoid needs to be replaced.

Cold is better because it will cause the heating element to activate which will increase the effectiveness of the brew rite.

If the spray head is clean and clear and you have run the spring the the brew tube till you can push it almost all the way in (leaving only 1/4") then it should not have issues.

This is a pour over brewer if it does not have a brew switch, you have to pour water into the top to brew the coffee.

you have to fill the tank with more than one carafe. Most of them are syphon/gravity fed machines meaning the cold water coming in forces the hot water out to brew the coffee. Hope this helps. WWW.MidstateBeverage.com

The Bunn coffee maker does not operate as most coffee makes do. You cannot leave the Bunn in the off position and then just flip the switch to on and pour the water in. You will always get cold coffee if you do this. It takes time for it to heat the water. The On/Off switch should be left in the On position all the time. This keeps the water hot in the tank, thus providing hot water when you need to make coffee. You then just pour the cold water in the top, shut the lid, and have a pot of coffee in 3 minutes. The On/Off switch is a vacation switch, and you use it only when you are not going to use the coffee maker for a couple of days. Older Bunn coffee makers did not even have an On/Off button. You simply unplugged them when going on vacation. So turn the switch to the On position and leave it there. The unit will then work as designed. Forget how other coffee makers work, this is a Bunn and it is the fastest coffee maker you can buy and must be left on all the time. that way the water stays hot and the unit will keep it that way.

Hello. I need to know if you have an automatic unit, or a pourover. The pourover will not have a timer at all. The difference is you have to pour the water in to get coffee out, an automatic would be connected to a water line, and you just push a start button. If it is an automatic unit, there has to be a timer somewhere to adjust the amount. Here is a web address that has your manual, and a parts breakdown should you need to find where the timer is located.

Hope that helped, and thank you.

It sounds like you have a pour over model and the problem is the tank isn't full. Turn the machine off (or unplug it). Put a pot on the warmer like you are going to brew coffee. Pour clean cold water into the top until it starts coming out the sprayhead (above where the coffee grounds go). Now plug it in and turn on. Let it heat up then you can brew.

The way your machine works is that there is always about 2-1/2 pots of water in the tank. The water you pour in to make coffee is actually pushing the hot water in the tank out. So, if you don't fill the tank before using it, you may be hurting the heating element since it isn't totally submerged in water.
