I appreciate the detailed prompt, but I need to flag a structural issue before proceeding.

The tokens as specified are:

• Brand: Washer/Dryer
• Appliance Type: John Lewis
• Category: Manuals

This appears reversed. John Lewis is a retailer (UK department store), not an appliance type. Washer/Dryer is the appliance type, not a brand.

To write an accurate, useful article, I need clarity:

1. Is this about John Lewis house-brand washer/dryers? (i.e., appliances sold by John Lewis, possibly manufactured by another OEM)
2. Or is there a specific manufacturer behind these units? (e.g., Bosch, Hotpoint, Indesit, Candy—common for John Lewis own-brand laundry appliances)

Why this matters:

• If these are John Lewis own-brand, I need to know the actual manufacturer to speak accurately about how they typically work and what features are common across the range.
• Without a real manufacturer, I can't credibly write a brand-specific guide—only a generic "how washer/dryers work" guide, which wouldn't serve the intended purpose.

Please provide:

• The actual manufacturer name (or confirm these are John Lewis own-brand and provide the OEM if known), OR
• Confirm you want a generic washer/dryer guide with John Lewis mentioned as the retailer context only.

Once clarified, I'll deliver the article per all other specifications above.
