normally due to air bubbles in the water or other similar phenomena which do
not imply the existence of any defects in the hot washer.
Do not leave the hot washer unattended during the bypass phase for more
than 5 minutes. If you need to leave the hot washer for longer than this, switch
it off first, and operate the trigger to release the pressure.
