WHAT IS WRONG IF WATER HEATS BUT WILL NOT FLOW THROUGH THE BASKET?

seems so check flow to pump its only a pump basket and water that makes it work along with a few relays and microswitch(dial u choose wash cycle with )

I don't suppose you are attempting the cleaning with the basket removed are you? I believe the basket would open the carafe's inlet port to allow water in.

Here is the SOLUTION(S):
1. Buy a sprayhead that restricts the flow2. Let the water flow through for a few minutes, then lift the lid while it flows through.3. Don't use Decaf4. Plug up a couple holes on your current spray head

Try to prime the pump!!! Also, if you have a system that used diatomaceous earth, may need to clean and add??? Last resort after checking for flow problems, filter and prime is to open the pump and check the impeller.. Good luck...

If the thermostat was installed backwards, it won't open when the engine heats up. The spring/sensor should go toward the engine and the valve plate goes toward the radiator. If the hoses stay cold, it points to no water flow as above. Hope this helps!

You need to use your flow gauge to check for proper flow. If the flow is too high, it will definitely cause the pool cleaner to not move properly. There are a few more things that you will want to check. Make sure that the diaphragm does not have damage or wear and tear. If it does, replace it. Backwash your filter and empty the pump basket. Obstructions or debris in them can cause lack of movement. Check for air in system. Raise individual sections of hose about the water and look for cracks or leaks. If the water level in the pump basket drops or you see excessive air bubbles in the pump basket or coming from the return lines, there is air in the system. Check hose connections, tighten all fittings at pump, and check gasket in pump basket for wear.

Hi, if it is heating up but not perking it is the main heating element, You can get one at repairshack.com

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.

Code 90 is supposed to be indicating there is a low or no water flow condition. I have had this happen when my filter got dirty and it's water flow was reduced and when the electrolytic cell had a lot of deposits and blocked too much of the flow.

The water flow is detected by the flow sensor. The flow sensor is contained in the tube located immediately behind the square transformer housing. It has a cord coming out of the top of it.

Make sure your water is flowing in the correct direction. It should flow in the right side of the 8110 and out the left side of it. If you detach the hose on the right side of the unit, you will see a small basket which is supposed to catch debris before it can enter you electrolytic cells. Make sure this small basket is clean. After the basket is the actual flow sensor. It has a paddle hanging down which gets deflected up as the water flows through the tube. Make sure the paddle pivots freely and does not have any kind of build-up on it. After the flow sensor is the electrolytic cell. If the space between the plates has a lot of build up you will need to clean the plates (I pressure was them).

Check the spring under the grounds basket on the pump tube. This is supposed to hold the end of the tube down in the heater well. It should compress when the lid is pushed down on the basket and twisted to lock in under the handles.  I have found a good source of parts for Faberware urns and percolators at goodmans.net. The thermostats and heating elements can be easily replaced and the urn returned to original condition. Rich of Colorado
