Dosing Pump Diagnosing

Verify dosing pump resistance is 1,744-ohms.  

If the dosing pump resistance is out of range, 

replace the dosing pump.  If the dosing pump has 

the proper resistance, run 

Service Mode Test 

19: Bulk Detergent Dosing Pump Test

 to verify 

dosing pump operation.  If the dosing pump does 

not operate during Service Mode test 19, test for 

120 VAC at the dosing pump wiring connector.  

If no voltage is present at the dosing pump 

connector, verify voltage at J802, pin 1 to 6 on the 

main board.  If voltage is present at J802, check 

the wiring from the main board to the dosing 

pump for continuity.

Dosing Pump Removal

1.  Remove backsplash assembly and main 

board (see 

Backsplash Removal

 under 

Control Panel Housing / Backsplash

 and 

Main Board

 in the 

Cabinet and Structure 

section of this guide).  Remove the top cover 

assembly (see 

Top Cover Removal

 under 

Top Cover

 in the 

Capacitor (For 600/605 

Models Only)

 section of this service guide). 

2.  The conduit can be removed by prying up 

from top cover where it connects to the 

dispenser box and slide to the right side of 

washer to get disconnect from dosing pump.  

Be sure the O-ring seal comes out as well. 

3.  Disconnect harness from pump.

4.  Remove the three hex-head screws which 

is holding the pump to the top cover lift to 

remove the dosing pump.

The dosing pump is located inside the 

backsplash assembly on top cover.  The dosing 

pump will draw the right amount of detergent from 

the bulk tank to the dispenser drawer where it will 

mix with water and flows into tub assembly.

The thermistor and harness come as one  

assembly that connects to the main board.  It 

comes with an O-ring that creates a watertight 

seal around the probe itself.  When reinstalling 

the thermistor, ensure the thermistor is seated 

properly.  If it bulges, it will not seal properly.
