how to identify a seven-rib dryer drive belt
have the stopped drum and any earlier belt failures checked before ordering. the linked Hutchinson belt is marked 7PH1971 / 1971H7 and has seven ribs in the PH/H profile.
1971 mm is its nominal effective-length designation, not a tension adjustment. the motor and tensioner are not supplied.

scope: the technician must check the tensioner and drum supports and use the exact belt route. WDH804N8SA requires authorised service with its flammable R290 circuit intact. do not stretch a different belt to fit.

steps
- stop the dryer
if the drum will not turn normally, switch off, let it cool and disconnect power safely. do not run it with covers off to watch the belt.
- give the repairer details
check the full model and product-number revision on the product page. describe the stopped drum and any earlier belts that slipped or broke. have the technician compare the complete old belt marking and rib count.
- have the drive checked
ask the technician to check the belt, tensioner and drum supports, then follow the exact belt route. the length marking is not a tension setting. do not stretch another belt to fit or handle spring-loaded drive parts yourself.
- have the repair checked
the technician should check the belt seating and normal drum operation with the cabinet closed. more slipping needs another check.
