The magnetic valve at the top rear can either be malfunctioning - in which case the water/steam draw will no longer work properly - or the valve body can be leaking. Replacing the magnetic valve is easy.
Note: This instruction also involves removing the top and side covers. However, this is only necessary if you want to do further repairs. You can just remove just the back cover if you are not doing any other repairs.
