Fisher & Paykel did not give the GWL08US a manual of its own — it published a service supplement, document 200434, to be read alongside the GWL03US book, and that supplement is explicit that what changed were the electronic modules, the machine size settings and wash performance rather than the mechanics. That matters on a service call today, because a GWL08US that has had a control module swapped from another SmartDrive will behave oddly until the size setting is put back to match the cabinet it is actually fitted in.
Key Features
- SmartDrive electronically commutated direct-drive wash motor
