Step 1
Clean the dirt receptacle if you notice a partial loss of suction. Wrap a plastic trash bag around the lower part of the unit. Grip the bottom of the filter through the bag and shake to dislodge any dirt into the bag.
Step 2
Turn the power on and check the suction level at each inlet, if you continue to experience low suction after cleaning the unit and the filter. If the suction varies, this indicates the line is only partially clogged. Locate the clog by first checking the suction of the inlet near the power unit. Continue to check each inlet until you locate the inlet with the loss in suction. The clog is in between the inlet with the loss of suction and the inlet you previously checked. Insert an electrician's fish tape into the inlet and push the clog through.
Step 3
Inspect the hose for an obstruction and remove it, if you notice a total loss of suction when the motor is running. Check all the inlets for loss of suction and remove any obstructions.
Step 4
Reset the breaker or replace the fuse on your home's electrical box if the motor will not start. If the control light is lit and the motor starts with the control switch but does not start at the inlets, this indicates a low-voltage wiring issue; contact your Beam dealer for assistance.
