Why does the coffee maker cycle but water does not run over the grounds in the basket?
First I'm not a Brewmatic tech, but I have worked on this and other similar brands. You should call your vendor for service. Especially if this equip is on loan. *** the following is for information only.***
* This brewer has a multiple timer selection as well as multi function. (it can brew in different ways and sizes.)
* The batch selector determines the brew time. This is set up according to your needs and the pots you will be using. If you change pots then the machine needs to be re-calibrated to the new sized pots.
* Each timer setting needs to be individually calibrated and checked. This is usually done by the tech. Some brewers can be set without taking the cover off but most are locked out by the vendor to prevent tampering. You will need the operator/tech manual to make adjustments. (check your MFR online site)
* There is usually 2 tubes from the tank (top) to the brew head. The 2nd tube which usually branches off the brewing tube is a by-pass port which will trickle down between the wire basket and funnel. This is why it is important to keep the metal wire basket inside the larger metal brew funnel. Some may come with a separate by-pass solenoid but most have a needle valve. I usually set this needle valve by closing it all the way down (clock-wise) and opening it back up 3 full turn (counter-clockwise) I've found and average of 3-1/2 turns works for most 1 gallon brews. Opening it more will give you more watery brew and closing it down a stronger and sometimes bitter brew. It really depends on your grind size and brew amount. You will need to test it at least 3 - 5 full brews to find the sweet spot. But, stick with 3-1/2 turns if your not sure.
* If there is a 3d tube , it usually runs to the hot water faucet which is gravity fed so it does not need a solenoid valve.
* Some brands may have one more tube that has a solenoid attached which usually runs to the middle of the brewer near the top of the decanter. This is the water by-pass for Iced tea. Tea brews into the funnel the same as coffee but the funnel has a smaller drip hole. This allows the tea to steep longer in the funnel. This tea concentrate is then cooled down with the addition of cold water from this extra middle port. Most brewers with the tea option has a taller appearance to fit the tall Iced tea dispenser.
* Final; the brewing spray head should fill with hot water unless the timer or brew solenoid is not working.
* Short brews can also be caused by water probe or water control board problems. Check the water probe for crud or fixed too low in the tank. Low water in tank will lead to slower brewing and longer brew times.
* Brews are also affected by water fill valves. Not opening or intermitent operation. Note some valves are not rated for hot water feed. If your connected to a hot water line then the inlet valve needs to be rated for hot water.
* Final, check if your operators are pushing the right batch size button. Call your coffee vendor for help.
