Sub-Zero Dishwasher Knocking During Wash Cycle in Houston, TX

Sub-Zero specializes exclusively in premium refrigeration — built-in refrigerators, freezers, and wine storage — using dual-compressor systems and magnetic door seals designed for decades of service, not laundry or cooking appliances (its sibling brand Wolf covers cooking). Even so, if you have a Sub-Zero-branded dishwasher, our technicians still service it — diagnosing spray arm clogs, drain pump faults, and door latch or control board issues the same way we would for any brand in this category.

Since Sub-Zero isn't a typical dishwasher manufacturer, original parts can take longer to source — we use OEM-compatible parts where the original brand's parts aren't readily available, so most repairs still run $120–$350.

In most Harris County zip codes we offer same-day service. Call before noon and we can usually have a technician at your door within 2–4 hours. We service all Harris County zip codes including 770xx, Katy, The Woodlands, Pearland, Sugar Land, Humble, and Conroe.

Yes. Our technicians stock the most commonly needed replacement parts for all major brands. Most Harris County repairs are completed in a single visit — no waiting for parts to be ordered.

We repair all major appliance brands including Samsung, LG, Whirlpool, GE, Maytag, Bosch, KitchenAid, Frigidaire, Sub-Zero, Viking, Kenmore, Amana, Electrolux, Miele, Thermador, and Wolf.
