Preventative Care Guide

Annual Dishwasher Maintenance Checklist

Four vital annual inspections performed by Duluth Appliance Repair specialists to prevent costly leaks, restore wash pressure, and extend equipment life across Gwinnett County homes.

Modern dishwashers rely on balanced water pressure, unobstructed drain loops, and calibrated electronic inlet valves to clean effectively and protect your cabinetry from moisture damage.

Follow this step-by-step preventative checklist to keep your unit operating at factory performance, eliminate lingering odors, and prevent premature component failure.

Task 01High Water Pressure

Spray Arm Descaling

Clears hard water scale & unblocks spray nozzles

Mineral deposits and calcium buildup from Gwinnett County tap water gradually plug spray jet nozzles, resulting in grimy glassware and poor wash coverage.

Action Checklist:

  • Remove lower and upper spray arms with a gentle counterclockwise twist
  • Inspect every tiny jet orifice for trapped food particles and lime scale
  • Submerge arms in warm descaling solution and clear ports using a soft wire tool
  • Verify spin rotation clearance and inspect the central manifold bearing seal
Pro Tech Tip: If nozzle holes are cracked or warped, replace the spray arm to prevent internal pressure drops.
Task 02Backflow Prevention

High-Loop Drain Hose Inspection

Prevents dirty sink water backflow & foul odors

A sagging drain hose allows contaminated sink water and garbage disposal debris to siphon back into the dishwasher wash chamber between cycles.

Action Checklist:

  • Check cabinet under-sink routing to confirm the drain hose loops at least 32 inches high
  • Inspect flexible ribbed hose for kinks, hairline stress cracks, and grease sludge
  • Tighten hose clamps at the garbage disposal inlet and check valve connection
  • Clean out disposal nipple to eliminate grease blockages before they cause code E24/drain faults
Pro Tech Tip: Duluth plumbing codes require either an air gap or a secured high loop right under the countertop.
Task 03Flood Protection

Water Inlet Valve & Solenoid Test

Guarantees proper fill volume & protects against leaks

The electronic water valve regulates intake pressure. Sediment-clogged internal mesh screens or failing solenoids cause slow filling or catastrophic flooding.

Action Checklist:

  • Shut off water supply and disconnect electrical harness to the bottom valve
  • Inspect brass inlet mesh screen for rust flecks, silt, and municipal debris
  • Test dual solenoid coils with a multimeter for standard 500-1500 ohm continuity
  • Check water fill level in the tub — proper level should reach directly below the heating element
Pro Tech Tip: Never attempt to clean a perforated internal screen; replace the entire valve assembly for leak safety.
Task 04Odor & Motor Life

Sump Basin, Filter & Float Sanitization

Restores maximum pump suction & drainage speed

The lower sump basin collects food fats, micro-debris, and biofilm that can bind the circulation pump impeller and cause stuck float switch errors.

Action Checklist:

  • Disassemble cylinder micro-mesh filter, coarse screen, and sump filter plate
  • Degrease basin floor and clear trapped seeds, glass shards, and debris from impeller inlet
  • Manually actuate overfill float switch to ensure smooth vertical travel without sticking
  • Sanitize sump walls and run a high-heat sanitizing cycle to purge hidden bacterial films
Pro Tech Tip: A sticky float switch will trick your dishwasher into continuous draining or total refusal to start.
