PLEASE REMEMBER TO TURN OFF THE POWER FIRST The aquastream shower looks more high tec than it really is . Take a flat head screw driver and place it behind the actual knob that turns on the water not the temperature knob and gently (but don't be afraid to put some muscle in gently) prise it towards you and off the shower unit itself . hey presto ! your looking at three cross head screws that you simply remove to release the temperature knob. Then remove the casing screw on top of the shower unit and your in.The most common problems are the micro switch on the control knob and the pump bearing sqealing because the hot water temp is to hot for the unit and causes a high pitched sqeal for a while and goes after you turn the controlback and forth. Great shower and i hope this helps.
