Our Bunn coffee maker has worked great for two years, but all of a sudden when we go to make coffee, the water pours out FAST and not the normal slow drip and the coffee is weak weak weak...we have cleaned thoroughly and not sure what do to do?

VPR 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.

Thanks So Much, Mike

This is common with bunn coffee makers, if you are not fast enough, coffee starts dripping. The only solution I found is to use a water pitcher, first fill coffee pot to cup mark you are using, then pour into pitcher, put pot back on machine, then pour in water. You can mark a line on picture, so you know where to fill to each time.

These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

You could have scale building up on the heating element and thermostat probe. try running a 1/3 white vinigar - 2/3 water mix into the brewer, let it heat up completely, then run several pots of clear water through the unit. keep pouring water through it until the vinigar smell is out of the water,

If you plugged it in before water started coming out of the sprayhead (about 2 pots full of water poured in) you might have burnt out your element, But lets start with a simpler answer. Did you check the main burner switch on the side of the tank?
If so, then I would suspect your main heating element

your problem is caused by the pour-in tray leaking where it mounts to the tank. There should be 2 screws under the pour-in lid, and a third toward the rear of the brewer. if you take them out & lift up carefully, you can see the pour-in tray. in the bottom of the tray, there is a bolt that mounts the tray to the tank. If you remove that, you can lift the pour-in tray out. Be careful, as these trays get brittle over time, and are prone to cracking.

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.
