Professional Advice

Repair or Replace Your Dishwasher?

The "50% Rule"

We believe in honest service. If your dishwasher is over 10 years old and the repair cost exceeds 50% of a new unit's price, we often recommend replacement instead of repair.

When to Repair

  • The unit is under 7 years old
  • Repair cost is less than 30% of replacement cost
  • The issue is a known "wear part" (seals, sensors, belts)
  • You are happy with the unit's performance otherwise

When to Replace

  • The unit is 10+ years old (15+ for Sub-Zero)
  • The repair involves a major component (compressor, transmission)
  • You have already repaired the same issue twice before
  • Replacement offers significantly better energy efficiency

Not sure? Our technicians provide a professional condition assessment during every diagnostic visit. We will tell you directly if we believe a replacement makes more financial sense for you.

FAQ

LG Dishwasher FAQ — Mercer Island, WA

Do you repair LG dishwashers specifically in Mercer Island?
Yes — LG dishwasher repair is one of the services we provide throughout Mercer Island. Our technicians arrive equipped with LG-specific diagnostic tools and commonly needed LG parts for dishwasher service. Standard scheduling is typically within 1–2 days.
How quickly can you schedule LG Dishwasher repair in Mercer Island?
Most LG dishwasher appointments in Mercer Island are available within 1–2 days. Same-day availability is possible for urgent situations — call before noon to check current slot availability in Mercer Island.
My LG dishwasher isn't cleaning dishes properly. What's causing it?
Poor cleaning usually points to a failing spray arm, low water pressure, or a clogged inlet valve. If cleaning the spray arm ports doesn't resolve it, a technician should inspect the water inlet valve and circulation pump. Hard water deposits accelerate this in LG dishwashers.
Is it safe to keep using my LG dishwasher if it's leaking?
No — stop using it immediately. A leak damages flooring, subfloor, and cabinetry rapidly if left running. Door seal failures and pump housing cracks are the most common causes. We can usually identify and repair the leak in a single visit.
Do you use genuine LG OEM parts for all repairs?
Always. We source genuine LG OEM parts through authorized distributors. Aftermarket components are not used for LG repairs — they often fail to meet the tolerance specifications required for LG systems. Using non-OEM parts on a LG unit creates performance and safety risks we won't accept.
How quickly can I get an appointment for Dishwasher repair in Mercer Island?
Standard scheduling in Mercer Island is typically within 1–2 business days. For urgent situations, call before noon to check same-day options in Mercer Island.
Do you provide a warranty on LG dishwasher repairs?
Yes — all repairs include a service warranty covering both parts and labor. The coverage details are provided in writing before work begins. We stand behind the quality of every repair.
