Almost a five — the control panel could be more intuitive

Love this dishwasher overall but spent way more time than I should have reading the manual to figure out how to run a delayed start. The panel layout isn't super intuitive. Everything works once you figure it out, but a more user-friendly interface would be a nice improvement. Cleaning performance is superb though, no issues whatsoever there.

Finally a dishwasher that handles our large plates

We have 12-inch dinner plates that wouldnt fit properly in our last two dishwashers, always had to angle them awkwardly. The rack configuration handles them easily. Cleaning results are excellent and the cycle options give us real flexibility depending on what we're washing. Love this appliance.

Bought it as a gift

Bought the Zline dishwasher as a gift for my brother and his wife. They called me two weeks later to rave about how quiet it is and how well it cleans. Apparently it's already replaced their habit of hand-washing everything

Great dishwasher, delivery experience was rough

The dishwasher itself is excellent. Very quiet, cleans thoroughly, looks premium. But the delivery was a mess. Arrived at the end of a much larger delivery window than promised, and the box had some cosmetic damage though thankfully the unit inside was fine. Once it was installed I quickly forgot about all that. Just plan for some delivery uncertainty.

Does what every dishwasher should do

I know that sounds simple but my last three dishwashers all had some annoying quirk. This one just works. Dishes are clean every time, the third rack holds utensils perfectly, and the dry cycle actually dries things. We've been running it nightly for six months and it hasn't skipped a beat.

nice machine, minor fit issue on install

the dishwasher itself is really solid. during install we noticed the side leveling was a bit finicky and took longer than expected to get truly level. nothing broke or went wrong, just added time to the job. once its in and level it operates perfectly. would buy again.

Quiet and effective, rack system has a learning curve

The quietness is everything people say it is. Gets dishes clean with no issues. The only adjustment is the third-rack layout, which took some trial and error to figure out the best way to load it. Once you get the hang of it you appreciate the extra capacity. Good dishwasher, just takes a wash or two to optimize your loading strategy.

Sleek, silent, spotless

We replaced a builder-grade dishwasher that was loud, slow, and left residue on glassware. The Monument is the opposite in every way. The hidden top controls give it a super clean look in our kitchen. Glasses come out clear and streak-free, and we can have a full conversation next to it while it runs.

Quietest dishwasher I've ever owned

The decibel rating on this is listed at 44 dB and I can confirm, you genuinely can't hear it running from the next room. After years of a loud dishwasher that interrupted every evening, this is a massive quality of life improvement. Dishes come out spotless too. The stainless tub feels very premium.

Solid product — handle finish could be more durable

Everything about this dishwasher performs as described. The one thing I've noticed is that the handle has some scratches from normal daily use after about six months. It's subtle but noticeable up close. Not a functional issue whatsoever. A durable handle finish would make this a five.

three kids, one dishwasher, zero complaints

We run this thing twice a day. With 4 kids in the house the amount of dishes we go through is absurd. This keeps up without any issues. The third rack for silverware is a game changer because it frees up the main basket for more dishes. Super quiet and consistently clean. Great appliance for a busy family.

This dishwasher actually gets everything clean

I had given up on dishwashers cleaning pots and pans and had resigned myself to always hand washing them. Thios dishwasher proved me wrong. The heavy duty wash cycle takes care of even baked on grease when I use the right detergent.

Diane Patel
Really good, one minor complaint about drying

The washing performance on the Monument is genuinely excellent. everything comes out clean, even stuff I half-expected to need rewashing. My only consistent gripe is that plastic items on the top rack don't always dry fully, even on the high-heat dry setting. Everything else does. Still a strong four stars and I'd recommend it.

Couldn't be happier

Purchased the dishwasher about eight months ago and it's been perfect. Runs so quietly you have to check the light to see if it's still going. Consistently cleans even the pots I was skeptical about. The third rack is genuinely useful and not just a gimmick. Top tier dishwasher for the price.

Lovely appliance, wish the filter was easier to clean

We clean the filter per the manual recommendations and it's a little awkward to access compared to our previous dishwasher. Not a big deal and probably takes five minutes once a month, but the previous one was simpler. The dishwasher cleans incredibly well and is blessedly quiet. Minor workflow complaint on an otherwise excellent machine.

Worth the upgrade from a budget brand

Our previous dishwasher was cheap and it showed. This unit feels like a different category of appliance entirely. The door has satisfying weight to it, the racks slide smoothly, and the stainless interior looks and feels premium. After almost a year of use there's no discoloration or odor in the tub. Excellent long-term performance.

Install was easy, performance is outstanding

I swapped out our old dishwasher myself in about 90 minutes. Standard connections, clear instructions, no surprises. Once it was running, immediately noticed how quiet it is compared to everything else I've used. Consistently hitting the temp range and everything comes out impeccably clean.

Happy with it, took longer to receive than expected

Backorder added about three weeks to our wait. That was frustrating during a kitchen remodel when we were without a working dishwasher. Once it arrived and was installed though, the quality was obvious immediately. The interior is spacious, it runs quietly, and dishes come out clean every time. Great product, just wish the lead time was better communicated upfront.

Darius Pope
New homeowner, first dishwasher purchase

Did a ton of research before committing to this. The combination of the quiet operation, the stainless tub, and the flexible third rack is what won me over. Now that it's installed I can say all three lived up to what was promised. The wash cycle I use most often takes just under an hour and cleans everything thoroughly.

Matches our ZLINE range perfectly

We went all in on ZLINE appliances during our remodel and wanted a dishwasher that matched the aesthetic. This fits right in, the stainless is the same finish family as our range and rangetop. But it's not just about looks it runs incredibly quietly and the cleaning results have been excellent across the board.

Awesome Dishwasher

This dishwasher cleans so much better than our 20 year old one ever did! Didn't realize how dirty my dishes were after using the old dishwasher. Yikes! This dishwasher is so quiet, cleans exceptionally well and love the third rack. Wasn't sure I would like the third rack, but it holds my measuring cups perfectly and they don't turn upside down and fill with water like the old washer. Has taken some getting used to figuring out where to put everything, but there are so many ways to customize the interior, it's not been a problem fitting everything - large and small. My husband installed it and had no problem doing so. Love this brand and loved buying from The Range Hood Store. Highly recommend both!!

Dishwasher review

From what I gather, it has a multi-filter system that helps with the water quality used in the machine. I feel a sense of relief knowing that my grandkids are eating off clean utensils. I used to spend extra time rinsing the dishes in the sink before loading them into the dishwasher, but now I'm content with simply removing the leftovers.

Z-line Dishwasher Review

We ordered this dishwasher for our new house. It arrived but it took us a while to install it because we were out of town for most of the winter. After a few weeks I had to call customer support because the black stainless panel started to look crooked. Customer service sent a video to fix it I just hope it doesn't happen again but thank you to customer service for helping us

Not Bad

This dishwasher fits in perfectly with the other Zline appliances in our room. The only thing I would point out is that when I open the door, it seems to drop too fast.

Dishwasher Review

Cleans well. Super quiet to the point we were not sure we turned it on. Kids still refuse to load the dishes in though. Once ZLINE makes a dishwasher that forces my kids to load it I will buy 5.
