Blitzhome BH-CDW1 Portable Countertop Dishwasher Review

The built-in 1.3 gal (5 L) tank is the reason to pick this machine. Fill it with the included pitcher, drop the drain hose into a sink or a bucket, and it runs with no hookup at all. That single feature is what makes it work in a dorm, an RV or a rental where nobody will let you touch the plumbing.

Use faucet mode when a tap is close by

A 1.5 m (4.9 ft) inlet hose connects to a standard faucet, and the machine heats its own water, so you connect it to the cold side only. Faucet mode saves you the refills; tank mode saves you the faucet hookup.

Cleaning on everyday loads

The 360° spray arm and the high-temperature wash, with a final rinse up to 167 °F, handle plates, glasses, mugs, cutlery and baby bottles well. One buyer on Amazon praises exactly this: how clean the dishes come out and how clear the glasses look.

Five cycles that cover real use

The cycle options are Economy, Fruit, Rapid, Standard and Strong. The fruit and vegetable rinse is a genuinely useful extra when counter space is short.

Drying and air refresh

There is a dedicated hot-air dry cycle, plus an air-refresh function that keeps the interior from going stale between loads. Treat the dry cycle as a head start rather than a finish line.

A footprint that fits a counter

The machine is 16.9 in wide, 17 in deep and 18.1 in high, so it sits under most upper cabinets. Measure the clearance for the top-fill lid and the drop-down door before you buy, because both need room to swing.

Quiet enough for an apartment

At 58 dB it runs at conversational level: noticeable in a studio, not disruptive. The transparent door and the interior light let you spot a badly loaded rack without opening it, and the basket and rack are stainless steel inside a plastic tub, with a removable filter and touch panel controls.

One buyer on Amazon raises drying performance as a complaint. The hot-air cycle helps, but expect to towel off a few items, especially plastic and anything with a concave base.

The app is the weakest part

Every cycle runs from the touch panel, so treat the BH-CDW1 as a panel-controlled machine and anything the app adds as a bonus.

Capacity is smaller than the marketing suggests

It is a five-place-setting machine, which means one or two people per load. The top rack is for cups and small items, and some taller glasses will not fit up there.

Detergent goes in a recess, not a dispenser

There is a small recess on the inner door rather than a standard dispenser. Full-size pods sometimes do not fit, so powder, liquid or a halved pod works better. There is no rinse-aid indicator.

Missing features and uneven quality control

There is no Energy Star rating, no child lock, no leak protection and no voice-assistant compatibility. One buyer reports units arriving used, damp or smelling bad, or with a spray arm that does not turn, and reports slow seller response. That is the specific complaint behind the negative brand coverage out there, and it is fair to name it. The counterbalance is that most ratings are four or five stars, and one buyer reports multi-year service. Even so, it is not a substitute for a full-size dishwasher.

These are the numbers a buyer will actually use, and what each one changes day to day.

What the numbers mean in use

A cycle uses about 1.3 gal (5 L) of water, so the real saving against washing a similar load by hand is water, not electricity. The 950 W draw means a grounded outlet matters more than the bill.

Size and weight in practice

At 26 lb the machine is light enough for one person to lift onto a counter, and the 16.9 in width leaves room beside it for a dish rack or a kettle. The 18.1 in height is the figure to check against your upper cabinets, because the lid and door need headroom above and in front.

The choice comes down to whether a faucet sits within reach of the 1.5 m (4.9 ft) inlet hose.

Tank mode, step by step

1. Put the drain hose into a sink, a bucket or a standpipe.
2. Loop the drain hose up high so dirty water does not siphon back into the tub.

Faucet mode

Pull-down and pull-out spray faucets usually need an adapter or an under-sink valve, so check your faucet before you buy. Use cold water only, and keep the inlet pressure within the range the manual gives.

Placement rules

Set the machine on a level surface, plug it into a grounded outlet, and skip the extension cord and the plug adapter. Keep it away from a stove or any other heat source, and leave enough headroom to open the lid and the door.

What to check when the box arrives

Turn the spray arm by hand to confirm it spins freely. Run an empty cycle before the first load, and keep the packaging until you have done both.

First-load tips

Load plates facing the spray arm, keep the top rack light, and use the right amount of powder or liquid rather than a whole pod.

Detergent and loading

Load plates facing the spray arm and keep tall glasses out of the top rack if they do not clear it. An all-in-one detergent covers the missing rinse-aid indicator.

Maintenance that keeps it working

• Run a hot cycle once a month.
• Leave the door ajar between uses so the tub dries out.

Noise in context

At 58 dB the machine is fine in a kitchen and audible from a studio living area. Run it before bed rather than during a call.
