valve head maybe? not really familiar with sanyo

[stufus]

Check the screw's that secure the coil head's are tight ,If so ,use a magnet to open and close all valves a couple of times.And check coil voltages when operating.
If that doesn't do it probably a new svk required.
Techguy might pop up with some insight.
Cheers
