Looking for the best commercial undercounter dishwashers? The world of commercial dishwashers can be a tricky place to navigate. There are the big names heading up the show. However, over the past decade more and more brands have appeared, and sometimes disappeared. With new, household names entering the commercial dishwasher market place, brands we’ve never heard of before and some dealers white labelling dishwashers, it really can be difficult to know which commercial undercounter dishwasher is best.

Because of the ‘new’ names making an appearance, some of the major industry players have improved their existing dishwashers or created whole new ranges. Using their wealth of knowledge and industry leading technology they are producing more affordable models. Reducing specification that isn’t always needed, particularly for smaller independent sites, can create very effective and affordable commercial dishwashers.

In between entry-level and top tier there are a whole range of models aimed at different establishments. With differing performance demands, and varying budgets here’s our pick of the standout undercounter commercial dishwashers currently available in the UK:

2022 Update:

2022 didn’t see a significant change in the commercial dishwasher market. A number of manufacturers dishwasher models had already had a recent range of upgrades. However, at Eco Catering, we made some changes. We introduced Maidaid into our range. There is good reason for this as they include a good level of specification at a good price point and they all come with a 2-year warranty as standard. So much so that one of their dishwashers is in our top 5 recommended undercounter commercial dishwashers. The feedback from customers so far has been great and we expect that to continue.

Yep, it’s another Hobart. But to be honest with the three ranges currently offered by Hobart, the FX, Ecomax Plus and this, the Ecomax, it is difficult not to pick a model from each. This is the latest Ecomax undercounter dishwasher, the Ecomax F504W and F504SW.  Hobart have improved the specification from the outgoing F502, giving customers the chance to buy a Hobart dishwasher when budgets are more restricted. ‘Perfect for sites that don’t need something all singing and dancing, this latest model has a better control panel and an improved efficiency and reliability. The interior has also been redesigned and now contains a pressed interior meaning the unit is easier to clean and less prone to dirt build up. German quality and efficiency has never been so affordable

 5. DC SD50

Affordable workhorse of a commercial dishwasher.

Rack Rating: 20 p/hr (360 plates) Rack Size: 500 x 500 mm (18 Plates) Wash Tank: 26.0 ltrs  Water Cons:  2.4 p/cycle Cycle Times: 180 secs.

+ Ability to choose your preferred specification, controlling your budget

Everything is an optional extra

Basic warranty, unless you pay extra

At the opposite end of the spectrum to the Hobart FX is the DC Standard range. Here we have the SD50. DC dishwashers come in a basic format with a lengthy options list, allowing you to add a break tank, drain pump and water softener. Other brands may give you this as standard but it is reflected in the price. And if you don’t need these features you can keep your spec. to a minimum and in doing so keep the purchase price down. It has an easy to use control panel and will give good, reliable performance. Not suited to environments that put a high demand on their machine but perfect for those who don’t need ultimate performance but instead want a decent, cost effective undercounter dishwasher.

Under Counter Dishwasher FAQs

What is the best overall commercial undercounter dishwasher?

As commercial dishwashers go, there are hundreds of products to choose from. However, here at Eco Catering Equipment, we really like the Maidaid C525WS commercial undercounter dishwasher. And the additional 2-year manufacturer warranty is an added bonus to what is a great product at a fantastic price point.

Are undercounter dishwashers worth it?

In a word. Yes. A commercial dishwasher is able to handle much more volume than a domestic unit. As a business owner in the catering industry or pub owner, having the ability to clean dishes to a high standard at scale allows you to spend more time with customers and running your business as well as saving you money on additional salaries for kitchen staff. An undercounter unit is also able to save some space by slotting into spaces underneath the preparation areas.

What should I look for in a commercial undercounter dishwasher?

When you’re looking for a commercial dishwasher, there are a number of features you should be aware of and looking into. These include the Rack Rating (how many plates the product can clean at a time), Rack Size, Wash Tank, Number of Cycles, Cycle Times and general efficiency.

Are commercial undercounter dishwashers the same size as normal dishwashers?

The main differences between commercial and domestic undercounter washers is the speed and overall capacity of the unit. Otherwise, domestic rack dishwashers are of a similar size in dimensions to commercial ones.
