Saeco vienna plus red solid light cannot prime water line

First try to prime the machine.
Turn on hot water and prime about 100 ml hot water. If the red light remain you have to change the flowmeter.

1. Make sure the drawer for coffee grounds is securely closed 2. make sure that coffee beans are loaded and are actually down into the machine (and not clogged at the top) 3. Make sure water is in the hopper. If so, "bounce: the hopper a few times to see if bubbles come out indicating air in the water line. 4. Turn on and hope for a green light. If not, re-check 1 through 3

Solid red light is a ventilate light.. Try Priming the machine to see if the light goes away.

Something may be in the flow meter. Its the while device between the water tank and the pump of the machine. You would have to open the machine and clean out the flow meter.

Also, if you haven't descaled the machine already, I would start there.

Run the hot water cycle for a few seconds to prime machine.

I had the same problem, two green flashing lights with one red (water) all 3 would just keep flashing and not turn solid. No coffee can be made or hot water. I could not pump prime. The problem was the steam wand was blocked with old milk residue. It needs unblocking or you will never pump prime. I could not unscrew the steam wand...so I let it sink in a glass full of hot water for a few minutes and then turned the water knob counter clockwise to push out the softened residue. After that, everything was good. When water started flowing out of the steam wand, the red light turned off and the green lights turned solid. The obvious answer to why you can't pump prime is there is a blockage somewhere and best to start with the steam wand. --Mabada

Hi
More than likely your grind is to fine and you are using oily beans (shiney). There is a small knob in the bean hopper. turn it down to the minus side. Turn the big knob to the # 18. If that doesn't work you are going to have to take the grinder apart and clean it.

Hi
Once you have finished steaming, turn the steam button off, then open the knob and let the steam out. The water pump will turn on again and bring the temp back down. When the pump changes tone, the light will go off and you can brew again. It takes less than 10 seconds.

Press hot water button then open valve, then push the valve knob in if that works take it back and tell them that the valve is damaged.

May be time for a new machine.

Its either the electronics or the boiler, or worse. Both.

Vienna's have a typical life expectancy of about 4 to 7 years. 10 years is very commendable.

If the electronics and boiler are both bad it will end up costing almost as much as purchasing a new machine.

Water line is clogged you will have to open machine and find where the line is clogged.
