Best Countertop Dishwashers for RVs & Van Life (2026)
A dishwasher in an RV sounds luxurious until you do the amp math. Most RV circuits are 30 A total — and with the AC, fridge, and water heater already running, you might have 5–8 amps to spare. The question isn't "which dishwasher is best" but "which ones actually fit the circuit."
We checked the documented wattage of every tank-fed countertop dishwasher in our database. Only models with built-in water tanks qualify — you're not running a faucet adapter in a moving vehicle, and many RV sinks don't have the right fitting. Here are the 6 tank-fed models ranked by circuit friendliness, with every amp figure calculated from manufacturer-documented wattage.

1. Farberware Professional FDW05ASBWHA 5L Countertop Dishwasher — Most circuit-friendly
Editor's choice Check price on Amazon
Farberware Professional FDW05ASBWHA 5L Countertop Dishwasher
Footprint (mfr)43.9 × 41.9 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
At 750 W (6.3 A at 120 V), the Farberware leaves the most headroom on an RV circuit. On a 30 A service with AC running at 13 A, you'd still be under the 80% rule. The 4.9 L/cycle water use is also the lowest among 5 L tank models — relevant when your fresh-water tank is finite. Key caveat: it appears discontinued at first-party channels, and no official noise figure exists.
Strengths (per specs & cited reviews)
- Lowest wattage (750 W / 6.3 A) — most circuit headroom
- Lowest water/cycle among 5L tanks (4.9 L)
- Tank + faucet documented in the manual
Watch out for
- No official noise figure — important in RV close quarters
- Appears discontinued — check availability
2. Hermitlux HMX-DW03 Countertop Dishwasher — Best capacity at safe wattage
Hermitlux HMX-DW03 Countertop Dishwasher
Footprint (mfr)42.8 × 42.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)4
900 W (7.5 A) is well within a 30 A circuit's budget, and 4 place settings means you can run dishes for two meals before needing to run a cycle. The 50 dB noise is the second-quietest among tank models — usable in a van or trailer where the dishwasher is 5 feet from your bed. Every spec is documented including a 15 cm clearance figure.
Strengths (per specs & cited reviews)
- 4 place settings — best capacity among tank-fed models
- 50 dB — quiet enough for RV close quarters
- 900 W sits comfortably on a 30 A circuit
Watch out for
- 42.8 cm wide — measure your RV counter carefully
- 7.5 A draw still needs load staggering with AC
3. Daan Tech Bob the Mini Dishwasher (2 place settings) — Quietest for close quarters
Daan Tech Bob the Mini Dishwasher (2 place settings)
Footprint (mfr)34.0 × 49.0 cm
Water sourcetank + faucet
Tank (mfr)3.9 L
Place settings (mfr)2
In a van or Class B where you sleep 3 meters from the kitchen, noise is everything. The Bob at 43 dB is quieter than most refrigerators. At 1,000 W (8.3 A), it's the highest wattage here but still fits a 30 A circuit with headroom. The 3.9 L tank and 3.8 L/cycle water use are the most water-efficient — real value when boondocking.
Strengths (per specs & cited reviews)
- 43 dB — run it at night in a van without waking anyone
- Lowest water use (3.8 L) — critical for boondocking
- Smallest footprint (34 × 49 cm) — fits tight RV counters
Watch out for
- 1,000 W / 8.3 A — highest draw among tank models
- 2 place settings only
4. HAVA R01 Compact Countertop Dishwasher
HAVA R01 Compact Countertop Dishwasher
Footprint (mfr)42.5 × 42.8 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
950 W (7.9 A) with a 5 L tank and documented specs. Functionally similar to the Hermitlux and ecozy (likely shared OEM platform). The 60 dB noise is a concern in RV close quarters — that's clearly audible through any interior divider. At 2 place settings, it holds less than the Hermitlux on the same platform.
Strengths (per specs & cited reviews)
- Well-documented specs including noise
- Tank + faucet at 950 W (7.9 A)
- 5 L/cycle documented
Watch out for
- 60 dB — loud for close-quarters RV use
- 2 place settings vs Hermitlux's 4 on the same platform
5. ecozy DW-CT200A Portable Countertop Dishwasher
ecozy DW-CT200A Portable Countertop Dishwasher
Footprint (mfr)42.8 × 42.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)—
950 W (7.9 A) on the same body as the Hermitlux and HAVA. For RV use, the missing noise documentation is a real problem — you don't want to discover a 60+ dB dishwasher in a 7-meter van. The missing place-settings and water/cycle documentation makes it hard to plan water budgets. If you're considering this platform, the fully documented Hermitlux is the safer bet.
Strengths (per specs & cited reviews)
- 950 W / 7.9 A — fits a 30 A circuit
- Tank + faucet flexibility
Watch out for
- No documented noise — risky for RV close quarters
- No documented place settings or water/cycle
6. COMFEE' CDC17P0AWW 5L Portable Mini Dishwasher
COMFEE' CDC17P0AWW 5L Portable Mini Dishwasher
Footprint (mfr)42.0 × 43.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
The COMFEE' CDC17's big problem for RV use is double: the manual never states an actual rated wattage (online '1200 W' is just 120V × 10A circuit math), and at 62 dB it's the loudest documented model in our database. Without verified wattage, you can't do reliable amp math — and in an RV, reliable amp math is everything.
Strengths (per specs & cited reviews)
- Major brand (Midea/COMFEE') — parts availability on the road
- 5 L tank + faucet documented
Watch out for
- Wattage unverifiable — can't calculate reliable amp draw
- 62 dB — loudest documented model, problematic in RV close quarters
Where our data comes from
We don't test dishwashers or RV electrical systems. Every wattage figure below comes from the manufacturer's own documentation — user manuals and official spec sheets — and links to its source. Amp draw is calculated as watts ÷ 120 V. Where a manufacturer doesn't publish wattage (COMFEE' CDC17), it's shown as unverified.
Use our RV Amp Calculator to stack this dishwasher against your other loads and check the total against your circuit. The 80% rule applies: on a 30 A circuit, you should stay under 24 A continuous.

Frequently asked
Can I run a countertop dishwasher on a 30 A RV circuit?
Yes — every tank-fed model here draws under 8.4 A. But you need headroom: on a 30 A circuit, the 80% rule means 24 A continuous. If your AC is pulling 13–15 A, fridge 2–3 A, and water heater 10–12 A, you're already at the limit. Stagger loads: run the dishwasher when the AC or water heater is off.
Will a countertop dishwasher work on a 15 A outlet?
The Farberware at 750 W (6.3 A) comfortably fits a 15 A circuit alone. The 900–1,000 W models draw 7.5–8.3 A, which is fine solo but leaves little room for other loads on the same circuit.
How much water does a tank-fed dishwasher use?
Documented figures: 3.8–5.0 L per cycle. If your fresh-water tank is 100 L (typical Class B), one dishwasher cycle uses about 5% of your water. For comparison, hand-washing the same dishes uses 20–40 L or more.
Where do I drain a countertop dishwasher in an RV?
The drain hose goes to your RV sink or directly into your gray-water system if accessible. Most models' drain hoses are 1.5–2 m long. The pump pressure is modest — you can't push water uphill far, so the drain point shouldn't be much higher than the unit.
Can I run a countertop dishwasher on solar/battery (inverter)?
At 750–1,000 W, you'll need a pure-sine-wave inverter rated for at least the model's wattage (plus startup surge). A 1,000 W dishwasher running a 60-minute cycle uses roughly 1 kWh — about 83 Ah from a 12 V battery bank. That's feasible with a sizable lithium setup but will drain a small battery bank quickly.
