YOU HAVE TO OPEN THE TOP TO SEE WHERE THE LEAK COME FROM, OVERPRESSURE VALVE, CONNECTIONS TO BOILER , O-RINGS, SEALS, SENSORS CONNECTED TO THE BOILER ETC. U CANNOT TELL FROM THE BOTTOM!! RUDY.KY

The flow meter is clogged or the sensor is broken and flowmeter needs to be replaced.

Could be the breaker does not match up with the required amperage for the machine or you could be grounding out somewhere inside the machine.

Yes the autofill is inside the control electronic box . If you know about electronic PCB board you migh need to replace a relay which is welded on the PCB board. Or you have toreplace the whole electronic contraol box which is expensive.

On the right side of the machine next to the serial number is the most likely spot for the NSF sticker or tag depending on the model of the machine it may only have an ETL listing.

Your problem could be one or two items (element or pressure stat or both). Remove the screw in the top of the P.stat(black or gray rectangle box with electrical wire going in from bottom about 4-6 inches long), lift the cover and check the terminals(turn power off). Make sure that there are no loose connections on the terminals.
On the element remove the wires that are connected to it and test with an Ohmsmeter.

The keypad needs to be programed. Depending on your model there will be a small toggle switch on the right side, just behind the connection of the hot water valve(you will have to remove the top panel). Move the switch to the left, then press the program button at which time all the lights will be lit. Using a measuring cup press a button you want to program until you get the desired amount, then press the stop button(when programed the light will turn off), repeat to program the other 3 buttons. When done program move the toggle switch to the right. If the machine does not hold the program then the flowmeter under the drain tray(silver box with 3 wires on top), is damaged. Either repalce the top or check the impeller in the flowmeter, the magnets might dirty.(Make sure water is turned off before openning the flowmeter.

If you're pump is working and your needle shows around 9 bars when running, most likely your Solenoid valve is bad. This can be caused from improper backflushing among other things.

You can use it without one but it would be best to install a water softener system like an everpure ql3 head with a 7S0 softener. That might run you about $200 installed.

Jason, have you tried cutting power off to the machine for 5 minutes?

notify manufacturer or return it

There could be a number of issues here. If the pump pressure reads 0 then that would suggest there is no power going to the pump. Does the machine hum when you press for a brew? If it does then the pump is receiving power. If you have changed the pump recently have you reset the pump pressure manually on the pump head? This is done by adjusting the nut (12mm I think?) anti-clockwise to increase the pressure. Clockwise to reduce it. Perhaps the pressure gauge is faulty? No water to the brew head if the water pressure is fine and the pump is working indicates a blockage in the group head. You will need to strip down the valve and clear the filter which is a small hole under the large nut... Make sure the water is turned off and the machine is cold and isolated before stripping out the valve.

If by spout you mean tea valve, it could be that the economizer mixing solenoid valve is set to deliver more cold water when mixing. As for the level the silver probe on boiler.

It's improperly wired. Part of that improper wiring is it's not grounded correctly. Get a licensed electrician to look at it..
