Steam Valve Problem

The steam knob has a problem in that the microswitch seems to be OK (i.e. it turns on the pump) but after a stroke or two of the pump it just hums as if there's a blockage. Recently descaled so that seems an unlikely cause. Wondered if perhaps the steam wand valve (diverter?) is defective. I've disassembled it but as yet have not removed the valve to examine it for defectiveness. Or am I on the wrong trail and the problem likely to be something else?

Thanks in advance for your help.

The steam wand on my sunbeam cafe series is not working

Is it still making the correct pumping noise? If so, unscrew the knob from the end and unblock the steam head and wand with a bit of wire.
If it doesn't sound like it is pumping, either the microswitch in the left-hand dial is faulty or the steam pump is dead. To test the microswitch, pull the steam dial off and try to get the switch to make a connection (it's hidden at about 2 o'clock in the housing). Failing that you're up for a steam pump... about $80.

Gaggia Titanium. Fault suggests ventilation required. Followed manual instructions, nothing happens. Tried rinsing, nothing happens. Tried hot water nothing happens? Have taken out and cleaned all pbvious...

Do you hear the pump working but no water flows?

You should select hot water (the third button from the right) and the display should say "hot water" at the same time it is saying VENTILATE --- open the steam valve all the way and the pump should start and you should see water from the steam wand.

If you don't hear the pump at all, then that is a different problem.

If you do hear the pump but still don't get any water with the steam valve open, then you need to prime the pump by using a turkey baster or the accordian pump that came with the Titanium to pump water into the valve where water from the tank goes. Remove the tank and use the turkey baster to pump water into that valve while the pump is running and the steam valve is open all the way with HOT WATER selected. the second water starts to come out the steam valve you want to stop the pump (turn the power off or turn the steam knob shut) and put the water tank back on and make sure there is plenty of water in the tank - then start the pump again by opening the steam valve all the way and let it pump water out the steam wand for a few minutes.

My Solis SL-90 has an issue where when you press the on button the pump starts. Also does anyone know if the 110V circuit board is the same as the 220V one ?

110v and 220v are not the same.
If the pump starts when you turn ton the machine the steam knob is out of adjustment. If you turn the knob to far you can do this. Remember that the steam knob does not close the steam off. It only pushes a needle with a seat on it to open. When you turn the valve off it allows the needle with a seat to stop the steam. Turning to far only moves the valve farther from the needle and pretty soon it will not open the needle.

My steam/hot water arm fell out along with no steam

Easiest way to get to it, remove the 2 screws in the bean hopper, and remove the hopper, there are a few screws under the water tank, this should give you access to the machine top. Check the end of the steam wand it might be blocked use a paper clip to clear it out. Run it under the faucet to make suree it is clear. Check the microswitch that is connected to the steam valve, It can be seen when you turn the knob to open the steam/hot water valve, make sure it is not stuck in the on position.

'Chugging' noise when trying to get flow of water from steam tube

You must press the hot water/steam button to make sure it is set on hot water. The chugging noise is the pump slowly putting water through the steam boiler for steaming. When you open the steam knob make sure it is all the way open, you will hear the microswitch click when you reach full open(test it out with the machine off). Red light also means heating and low on water, since you are using all the steam faster than it can make it hence the red light.
