Important Tips for Roper Models

  • Roper washers commonly use an agitator repair kit or drive block replacement to fix non‑agitating symptoms; check model parts lists for compatibility.

Possible Causes

Worn or broken agitator components (agitator dogs or splines)

How to Identify: Agitator doesn’t engage properly; may spin loosely by hand; upper agitator moves freely or with little resistance.

Part: Agitator dogs / agitator splines

Worn drive block or coupling between transmission and agitator

How to Identify: Transmission may operate but agitator barely moves or rattles; visual inspection shows wear on drive block.

Part: Drive block / coupling

Worn motor coupling

How to Identify: Washer fills and drains normally but neither agitates nor spins; motor may run but motion isn’t transmitted.

Part: Motor coupling

Broken or loose drive belt

How to Identify: Visual inspection reveals belt slack, wear, or break; washer may make unusual sounds or agitator remains still.

Part: Drive belt

Faulty lid switch

How to Identify: Agitator doesn’t activate unless lid is fully closed; lid switch test fails continuity check.

Part: Lid switch assembly

Transmission or motor failure

How to Identify: Motor hums or fails to run; agitation system does not engage despite other components being intact; unusual noises from transmission.

Part: Transmission or drive motor
