Verdict
Sitting flush with your kitchen counters, the LG LDNPM654S FlushFit Dishwasher is a smart dishwasher with a lot of power. It’s generally very flexible, with a neat top rack that can go in three positions; however, it would be nice to have a cutlery rack at the top with a sliding section for taller glasses. Cleaning performance is very good, with Steam an option for heavily soiled items.

Key Features
Introduction
Packed with some clever features, including smart control and an innovative QuadWash Pro cleaning system, the LG LDNPM654S FlushFit Dishwasher is a great dishwasher. Sleek and stylish from the outside, this FlushFit model won’t stick out from your counter, giving a neat finish.
A little more rack flexibility would have been useful, but aside from that, this dishwasher covers most of your bases.
Design and features
- Works with LG ThinQ
- Three racks
- Clever adjustable cutlery rack
LG LDNPM654S FlushFit Dishwasher, as its name says, is designed to fit flush with your counter and doors. Just slide it into place, and the neat stainless steel door doesn’t protrude, giving a neater finish.
Controls are all available via the top of the door, so it’s easy to set this dishwasher. There are the standard modes you’d expect: Auto, Normal, Heavy, and a fast 1Hour option.
There’s also a Downloaded option that lets you add an extra cycle, available through the LG ThinQ app. Using this app is handy, as you get notifications when a wash cycle has finished, and don’t need to be near the dishwasher.
For each cycle, there are some additional options: Steam adds steam at the start of the cycle to improve wash performance; Dry Boost (two levels) adds heated drying to the mix; and High Temp boosts the water temperature for deeper cleaning.
The inside of the dishwasher is nicely laid out over three racks. The lower rack is where plates and bigger dishes go.
Evenly spread tines will take everything from small plates to large bowls, holding everything apart for thorough cleaning.
There’s also a silverware basket that runs the entire depth of the rack. You won’t necessarily need this as there’s a top cutlery rack, but it’s nice to have the extra space for when needed.
With the top rack, you get a flexible space, and the comfortable handles give you three height options, so you can balance the space below with the space on top. However, as the top cutlery rack doesn’t have much adjustment, you may struggle to fit big plates and tall wine glasses at the same time.
LG provides some foldable tines on this rack, and useful glass holders, which can be folded and tucked out of the way if they’re not needed.
On the top is the cutlery rack.
I like the slider on the left, which adjusts the height of half the basket, allowing more space for kitchen implements, such as ladles or spatulas. If you’ve ever struggled to fit everything in, this little feature is a lifesaver.
QuadWash Pro uses high-pressure jets, which LG says gives 38% more cleaning power than standard QuadWash.
Performance
- Cleans well on most cycles
- Good running costs
- Heavy load deals with tough stains.
I tried the LG LDNPM654S FlushFit Dishwasher out with all of its standard cycles, starting with the Normal wash. Here, I found this cost a reasonable 15c to run. Cleaning performance was generally good.
Simpler items were easy to clean, such as dirty coffee and tea mugs.
My dirty bowl with mac-and-cheese in it also came up clean, as did the cutlery I’d used.
This cycle did struggle with the microwaved scrambled egg, leaving quite a bit of mess behind.
Next, I moved to the Auto wash, where the LG LDNPM654S FlushFit Dishwasher automatically adjusts to suit the level of soiling. This increased the cycle to 27c, although cleaning performance was better with the egg bowl coming up mostly clean, with just a few faint marks on it (the other dishes cleaned perfectly).
With the Heavy wash, the cycle cost increased to 48c, with the steam option adding extra cost. However, the steam option and higher temperatures do improve cleaning a lot for heavily soiled items, and my egg bowl was completely clean this time, showing that this cycle is ideal for very dirty items.
Finally, I ran the 1Hour cycle, which is good for lightly soiled dishes, including coffee and tea mugs. This cycle costs 21c to run, so it’s not as efficient as the Normal cycle, but it is handy if you want to clean dishes quickly.
Should you buy it?
You want a neat, powerful dishwasher
Plenty of space inside, the dishwasher looks neat when installed and has efficient day-to-day cycles, plus powerful cleaning options for heavily soiled items.
You need even more flexibility
If you need more flexibility inside, look for a dishwasher that has a sliding cutlery rack at the top, giving more space below.
Final Thoughts
Efficient when you need it to be, and powerful when you have heavily soiled dishes, the LG LDNPM654S FlushFit Dishwasher is a great choice for busy households. I like the FlushFit design, helping maintain a streamlined kitchen, and found the dishwasher mostly flexible, although a more adjustable cutlery rack would have been useful.
