Combo unit won't drain? We clear pumps, fix hoses, and restore drainage. Same-day service, 90-day warranty. Average repair cost: $100–$300. Some causes are DIY-fixable — see below.
Novato's soft water supply and suburban housing stock create generally favorable conditions for combo drainage, with issues primarily from aging plumbing and ADU installation quality. Suburban tract homes built around 1978 in Bel Marin Keys, Indian Valley, and Pacheco Valley have plumbing approaching 48 years old — newer than many Bay Area cities. North Marin Water District delivers soft water at 40 TDS, keeping pump internals mineral-free. The warm 86°F summer climate causes moderate rubber hose deterioration in garage installations. ADU construction adds combo installations where drain connections may not meet optimal grade specifications.
Novato's soft North Marin water at 40 TDS and relatively newer 1978-era plumbing create favorable drainage conditions. The 86°F summer heat causes moderate hose wear. ADU construction adds installations where drain engineering may be suboptimal.

In Novato, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's control board relay: thermal cycling stresses solder joints on the relay contacts of the main control board, causing intermittent function switching failures If the unit randomly fails to switch between wash and dry modes, the control board relays may have cold solder joints
In Novato, very low mineral content (<60 ppm tds) or sodium-softened water causes over-sudsing, rubber swelling, and reduced detergent rinsing. This can affect your appliance's drain pump filter: over-sudsing from soft water creates dense foam that traps small objects and debris in the pump filter more quickly Clean the drain pump filter every 5 loads when using soft water; reduce detergent by at least 50%
