Mountain View's moderate water hardness and booming ADU construction drive combo drainage issues shaped by mineral buildup and secondary-structure plumbing quality. Ranch homes built around 1965 in Cuesta Park, Rex Manor, and Old Mountain View have standard residential drain infrastructure, but City of Mountain View blended water at 250 TDS deposits mineral residue inside drain pump housings over time. The explosive ADU construction near Google's campus and along El Camino Real creates new combo installations where drain connections to the main sewer line may be undersized or inadequately graded. Mountain View's apartment inventory near the North Bayshore area uses combo units in compact closet configurations where drain routing is constrained.
Mountain View's blended water at 250 TDS introduces moderate mineral content that affects drain pump longevity. The 1965-era ranch homes have standard drain infrastructure. Explosive ADU construction creates combo installations where drain engineering may be inadequate. Apartment development near tech campuses adds compact installations with shared drain stacks.
Clogged drain pump
Kinked drain hose
Failed pump motor
Filter blockage
Control board error
Combo units generate more lint during the wash-dry transition, and the filter catches debris from both cycles. Bay Area water hardness adds mineral scale that binds lint into stubborn clogs. Many combo unit owners do not know where the filter is located for cleaning.
Cost: $100–$180 | Time: 25-40 minutes
Combo units installed in Bay Area closets and under counters often have drain hoses bent sharply to fit the space. The corrugated hose kinks at bends and accumulates lint and soap residue internally, gradually reducing flow until drainage stops entirely.
Cost: $80–$160 | Time: 20-35 minutes
The drain pump runs during both wash and dry cycles in combo units, accumulating more operating hours than in a standalone washer. Motors burn out from running against partial blockages. You will hear humming during the drain cycle with no water movement.
Cost: $150–$280 | Time: 45-70 minutes
The control board may fail to send the drain signal due to a sensor error or software glitch. The unit completes wash but never initiates the drain cycle. Unplugging for 2 minutes sometimes clears the error, but persistent failures need board repair.
Cost: $150–$300 | Time: 40-60 minutes

In Mountain View, 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
