Key takeaways

  • Check exact washer, dryer and stacking-kit compatibility before ordering. Includes an approval worksheet and a replacement-machine example.

Do not stack a washer and dryer from different brands unless the appliance manufacturers explicitly approve the exact pair and the required stacking system. Matching widths, a familiar badge, or a kit advertised as universal do not establish compatibility. Until the model numbers and kit have been confirmed together, plan for a different layout.

This guide helps you assemble that confirmation before purchasing a replacement machine. It is a compatibility worksheet, not lifting or installation instructions. It also applies when two machines share a brand but come from different generations.

Start with three model numbers

Write down the full washer model, full dryer model, and proposed stacking-kit part number. Include letters after the main number: a shortened retail name may cover more than one configuration. Photograph labels only where safely accessible; do not pull out a connected appliance just to reach a rear label. Your receipt or registered-product account may supply the missing information.

Keep the existing kit in the list even if you intend to reuse it. A replacement washer can change the approved combination while the dryer remains unchanged. The question is whether this particular assembly is supported, not whether the old installation appeared steady.

LG’s US stacking guidance says only selected sets can be stacked, requires compatible models and the stacking accessory, and warns against a one-person stacking attempt. That guidance does not approve another manufacturer’s washer simply because its cabinet looks similar.

Use this approval worksheet

Complete one sheet for each proposed appliance pair
Field What to record Unresolved result
Washer identity Full model and country of sale Do not select the kit yet
Dryer identity Full model and country of sale Do not assume the series is enough
Approved kit Part number and applicable revision Request the official compatibility list
Pair approval Document naming both models, or written manufacturer confirmation Keep the stack unapproved
Room requirements Stack dimensions, clearances, utilities and access from installation documents Have the installer assess the location
Installer confirmation Exact equipment listed on the installation order Resolve before delivery

Save the document itself along with its link and the date checked. A screenshot of a generic accessory listing is weaker evidence than a compatibility document that identifies your appliances. If a seller changes the proposed kit, reopen the worksheet rather than carrying over the previous approval.

What “universal” leaves unanswered

Treat universal as the start of a question: universal within which product range, sizes, years and market? It may describe several machines from one manufacturer. It does not, by itself, identify the washer top, dryer feet, fasteners or installation conditions covered by the kit.

As a concrete example, AEG’s Irish support article about mixed-brand stacks limits its compatibility statements to Electrolux Group appliances and discusses matching the dryer feet to the connection kit. This is a regional example of a manufacturer’s scope, not approval of a US appliance pair.

A strap, rubber mat or improvised shelf is not evidence that the appliance manufacturers approve a direct stack. An independently supported appliance stand would be a separate installation question, requiring its own rated design and professional assessment; it is not a shortcut through this worksheet.

A worked replacement example

Illustrative scenario: a household owns dryer D-100 and washer W-100. The washer fails, and a shop offers W-200 from another brand. Both washers are advertised as 27 inches wide. The old kit label reads K-10.

  1. Record D-100, W-200 and K-10 as the proposed combination.
  2. Find that K-10’s document lists W-100 but not W-200.
  3. Ask the relevant manufacturers whether a different approved kit supports D-100 with W-200.
  4. If no approval is supplied, mark the stack unconfirmed and remove it from the purchase plan.

The equal widths do not change step four. The useful result is avoiding an unsuitable order before the machines arrive. Alternatives to price include an approved replacement washer, a compatible pair, or a side-by-side arrangement that fits the room and utility requirements.

Send a question that can receive a definite answer

Use this wording: “Can washer [full model] support dryer [full model] in a stacked installation in [country]? Which exact stacking-kit part number and installation document approve the combination? Does that answer change when replacing only the washer?” Attach the accessible model-label photographs and proposed kit details.

If the reply only says the appliances are the same width, ask for the compatibility reference. If support cannot confirm the pair, keep that response with your notes and choose an arrangement they can confirm. A retailer’s willingness to deliver is a separate matter from appliance compatibility.

Finish the room check before ordering

Approval of the pair is only one gate. Give the installer the closet opening, ceiling height, access route and utility locations. Ask them to check the combined installed height, door operation, ventilation requirements and service access against the exact documents. Avoid applying one generic clearance number to every machine.

Your final purchase record should contain one consistent set of model numbers across the quote, kit, manufacturer confirmation and installation booking. A substitution on delivery day means the compatibility decision must be checked again. Stop before lifting or connecting anything if the supplied equipment differs.
