Mobile RV Washer and Dryer Repair Across Florida
RV washer/dryer combo units are purpose-built for the 24-inch closet and the limited 120V power budget of a mobile coach. When they fail, the parts pool is narrow and the diagnosis is specific. We know these units and carry the most common failure parts.
The 24-inch ventless washer-dryer combo units found in most American RVs are condensing dryers - they use a heat exchanger to condense moisture from the drum air rather than exhausting it through a vent. This means they require cool water supplied through a secondary cold-water inlet during the drying cycle to chill the heat exchanger. An owner who connects the cold supply but leaves it at low pressure will find drying times are two to three times longer than the manual states.
Why the Washer Stops Mid-Cycle and Won't Drain
A combo unit that stops mid-cycle and shows a drain error has almost always encountered a blocked or failed drain pump. The pump is a small centrifugal impeller driven by a separate motor, and it can be blocked by foreign objects - a coin, a button, or compacted lint from inside the drum - that jam the impeller. The pump motor then overheats and the unit's thermal protection shuts it down.
The drain pump is accessible through the front service panel on most Splendide and LG 24-inch units. Jesse removes the pump cover, clears the impeller, and tests the motor under power before declaring the pump failed and requiring replacement. In many cases, clearing the impeller restores full function. When the motor winding has been damaged by the overload, replacement is necessary.
Why the Combo Unit Takes So Long to Dry
A condensing dryer that takes three or more hours to dry a small load has one of two problems: insufficient cold water flow to the heat exchanger, or a blocked condenser lint filter. The heat exchanger works by cooling the humid drum air with the incoming cold water supply. If water pressure at the cold supply is below 15 PSI, the exchanger runs warm and condensation is incomplete - moisture returns to the drum instead of draining out.
The lint filter is the other throttle point. Unlike a vented dryer where lint exits with the air, a ventless condenser unit accumulates lint on the heat exchanger fins and in the pump filter. A filter that has not been cleaned in 30 wash cycles reduces airflow enough to cut drying efficiency in half. Triton RV Repair cleans both the heat exchanger and the pump filter on every dryer service call.
Vented Versus Ventless - What Florida Owners Need to Know
A vented dryer exhausts humid air directly through a duct to the exterior of the coach. It dries faster - typically 45-60 minutes for a small load - and does not require the cold water heat exchanger. The drawback in Florida is that it exhausts interior conditioned air outside, which the AC must replace. In summer, a vented dryer running for an hour is effectively competing with the air conditioner.
A ventless condenser dryer recycles interior air and drains the condensed moisture through the plumbing. It takes longer but does not exhaust expensive conditioned air. For full-timers in Florida who run AC constantly, the ventless unit is the more energy-efficient choice despite the longer cycle time. Understanding the tradeoff helps owners calibrate expectations rather than diagnosing a fault.
Cleaning a Clogged Drain Pump on a Combo Unit
The drain pump filter on a Splendide or similar combo unit is accessed from the lower front panel. The panel usually snaps off or is held by two screws. Behind it is a small threaded cap - the pump filter - and a drain hose with a clip. Before opening the filter, Jesse places a shallow pan under the access point and opens the drain hose to empty trapped water in the pump. Only then is the filter unscrewed and the impeller housing inspected.
The most common blockage on Florida combo units is a combination of lint and fine sand from beach or campground sites. This mixture packs into the impeller more tightly than lint alone and requires the impeller to be turned by hand to clear it. Owners who clean the filter every 20 cycles avoid impeller jams entirely. Jesse demonstrates the procedure at the end of every pump service call.
Washer Fills but Won't Agitate
A combo unit that fills normally but then sits without beginning the wash cycle has either a motor drive problem or a stuck door latch interlock. The interlock is a safety switch - the machine will not begin agitation unless it confirms the door is fully latched. A door latch that is worn, misaligned, or mechanically stuck can fail to actuate the switch even when the door appears closed and latched.
If the door latch is confirmed functional, the motor drive board is the next component. The drive board on a combo unit controls both wash motor speed and drying heat. A failed board produces a fill-but-no-start condition because the motor cannot receive its run command. Control boards run $280-620 and are brand-specific; Jesse confirms part availability before diagnosis on vintage units.
Lint Filter Maintenance on a Ventless Dryer
The lint filter on a ventless condenser dryer has two components: the door lint screen, which catches large particles and is cleaned after every load, and the heat exchanger lint filter at the pump inlet, which is cleaned every 20-30 cycles depending on what the manufacturer specifies. The door screen is familiar to anyone who has used a standard dryer. The heat exchanger filter is the one that owners most commonly miss.
In Florida, where coaches are used year-round and laundry cycles accumulate faster than in seasonal use, the exchanger filter should be inspected monthly. A filter that has never been cleaned on a unit with 200 cycles of use is coated with a felt-like mat that restricts airflow severely. Clearing this filter on a neglected unit often restores drying time from three hours to the manufacturer's stated 60-90 minutes without any other service.
Service Pricing
| Service | Notes | Typical Range |
|---|---|---|
| Service call + washer/dryer diagnosis | Includes cycle test, drain check, and thermal limiter test | $299 - $399 |
| Drain pump replacement | Most common combo unit failure; covers fill-but-no-drain symptom | $155 - $310 |
| Door latch / interlock replacement | Safety interlock; machine will not start without it | $95 - $195 |
| Heating element replacement (dryer) | Ventless condenser dryer element; all heat complaints start here | $120 - $260 |
| Main control board replacement | When pump and element are good but unit won't complete cycles | $280 - $620 |
| Full unit replacement (combo) | Splendide or LG 24-inch; includes connection and leveling | $650 - $1,500 |
Pricing transparency: All prices are estimates based on typical coach configurations. Labor-intensive access situations, custom coach layouts, and parts availability affect the final figure. The service call fee of $299 - $399 covers diagnosis, testing, and the first hour of labor.

Frequently Asked Questions
What causes an RV washer to stop mid-cycle and not drain?
A combo unit that stops mid-cycle and shows a drain error has almost always encountered a blocked or failed drain pump. The pump is a small centrifugal impeller driven by a separate motor, and it can be blocked by foreign objects - a coin, a button, or compacted lint from inside the drum - that jam the impeller. The pump motor then overheats and the unit's thermal protection shuts it down.
Why does my combo unit take so long to dry clothes?
A condensing dryer that takes three or more hours to dry a small load has one of two problems: insufficient cold water flow to the heat exchanger, or a blocked condenser lint filter. The heat exchanger works by cooling the humid drum air with the incoming cold water supply. If water pressure at the cold supply is below 15 PSI, the exchanger runs warm and condensation is incomplete - moisture returns to the drum instead of draining out.
What is the difference between a vented and ventless dryer in an RV?
A vented dryer exhausts humid air directly through a duct to the exterior of the coach. It dries faster - typically 45-60 minutes for a small load - and does not require the cold water heat exchanger. The drawback in Florida is that it exhausts interior conditioned air outside, which the AC must replace.

My washer fills but will not agitate - what failed?
A combo unit that fills normally but then sits without beginning the wash cycle has either a motor drive problem or a stuck door latch interlock. The interlock is a safety switch - the machine will not begin agitation unless it confirms the door is fully latched. A door latch that is worn, misaligned, or mechanically stuck can fail to actuate the switch even when the door appears closed and latched.
