HOW TO USE THIS REPAIR GUIDE

The instructions in this Repair Guide pertain to the Bissell PowerSteamer ProHeat (#1698) and the Bissell ProHeat ClearView(#1699). The information identifies those parts and components which are most likely to cause problems in the operation of the unit. Using easy-to- understand diagnostic procedures and step-by-step repair and/or replacement instructions, you will be able to identify and repair a wide variety of common repair problems.

UL RECOMMENDED HIGH VOLTAGE TEST

In keeping with UL standards, a high voltage test should be performed on a vacuum or deep cleaner any time the unit is in for repair, particular when the motor or other electrical components have been replaced. High voltage testing is done for the safety of the customer. By applying an over-voltage between "live" parts and various metal portions of the machine that are exposed to wear, you proof-test the entire machine against grounds or shorts that could cause inconvenience, fires or personal injury. High voltage testing is also a quality control measure. The possible future failure in the insulation of any portion of the unit, whether due to workmanship, components or materials, will be detected by this procedure prior to return of the unit back to the customer.

The normal test parameters are 1000 volts for one minute. There must be no indication of dielectric breakdown at the uppermost values. After the unit is completely assembled, the high voltage test required is the power cord to terminals in plug with the product switch on "on" position. This test can be accomplished with any commercial available test equipment offered for this purpose. The following testers are recommended:

Associated Research - Model 4025 or 4050 AJ

Slaughter - Model Series 2306 or 2307

Beckman Ind (Rosemont) - Model P-9A

Ground Continuity Test

This test is performed to determine that grounding continuity exists between the grounding blade of the lower supply cord plug and the motor. This test should be performed any time electrical connections are disturbed. Any suitable indicating device - ohmmeter, battery/buzzer combination or the like may be used to determine compliance. Contact points are the ground terminal in the plug to the shaft of the vacuum motor and the heater body.

USING THE SERVICING PLATFORM

Begin by placing the unit on the Servicing Platform. Servicing Platform should fit securely under the unit and raise its wheels off the servicing surface.

PRELIMINARY DIAGNOSTIC CHECKS

1.Test the trigger mechanism. There should be 1/4" of free travel before 1/4" of resistance. If not, ensure that valve is seated correctly. If valve is OK, replace the trigger rod.

2.Check resistance of the SmartMix knob by turning it from left to right several times. If difficult to turn, check to see that the piston is installed correctly (with housing removed).

3.Check seals on Clear Water Tank and Solution Tank. If necessary, re-seat or replace seals.

4.Check valve action on Clear Water Tank and Solution Tank by depressing them with your finger. The valve should move up and down. Replace if necessary.

5.Check position and condition of gaskets at nozzle window top and motor duct. Re-seat or replace if necessary.

6.Check position of tabs (2) at upper rear of nozzle window to ensure they are inserted properly into their alignment holes. Re-seat if necessary.

7.Remove belt access door at left front of unit (viewed from rear).

8.Manually rotate motor shaft to determine that motor, brush and pump are moving smoothly and quietly.

9.

 

may be hindering the free movement of these components.

 

 

 

FUNCTIONAL SYSTEMS CHECK

1.Fill tank bladder and solution bottle 1/2 full with clean water.

2.Set smart mix knob to NORMAL.

Set diverter knob to "Carpet." Turn on "power" and "heat." Make certain heater light is "on" (front of unit).

3.Listen for unusual motor noise such as grinding, racing, louder than normal, etc. If so, replace motor.

4.Depress trigger -- watch for spinning flow indicator. If flow indicator does not spin, ensure that it is assembled properly. If it is and the problem persists, refer to the sections on "TAKING THE UNIT APART" and "TROUBLESHOOTING THE FLOW SYSTEM."

5.Make certain water is being suctioned back into the unit. If not, check the position and condition of gaskets at the top of the nozzle window and the motor duct. Re-seat or replace if necessary.

6.Install upholstery tool to end of hose and depress spray button.

7.Make certain it sprays and that water is being suctioned back into the unit. If not, inspect and correct any pinched or kinked tubing.

TAKING THE UNIT APART

1.Unplug the unit.

2.Recline the handle backwards fully.

3.Turn SmartMix to "normal" traffic setting.

4.Remove the Solution and Clean Water Tanks.

5.Remove clear flow indicator cap, red spinner and filter.

6.Remove the two screws in the nozzle window and lift the front of the window straight up to remove.
