The True Cost of Commercial Dishwashers: What You Need to Know

It’s a common mistake, but too many people still purchase a commercial dishwasher based solely on the initial investment price. While the upfront cost is a significant aspect, it’s only one part of the broader picture. We’re here to help you understand the true cost of your commercial dishwasher.

In fact, the lifecycle cost of any machine includes installation expenses, the cost of regular maintenance and unexpected repairs, extended warranties, and ongoing operating costs such as detergent, rinse aid and energy consumption.

Understanding these costs can help you make well-informed financial decisions that optimise operations and ultimately ensure a return on investment.

COMMERCIAL DISHWASHER INSTALLATION COST

When purchasing a commercial dishwasher, it’s crucial to remember the installation cost. This aspect isn’t usually included in the purchase price, and overlooking it can lead to unexpected expenses that significantly strain your budget.

Installation extends beyond simply positioning the machine. It involves considerations such as electrical and plumbing work, construction or modification of existing spaces, and in the case of passthrough dishwashers, the need for bespoke fabrication.

For example, services (water, waste and electrics) need to be situated within one metre of the machine for installation to proceed. Services in unsuitable locations must be relocated, and the cost will depend on labour requirements and any additional equipment needed.

Passthrough (also known as hood-type) dishwashers often require bespoke fabrication such as entry and exit tables and specialised wash-up areas. You can usually expect to pay between £1,000 and £5,000 for this type of work.

Labour costs depend on the complexity of the installation, the time required, and the number of engineers needed. Labour typically ranges from £175 to £500 for undercounter dishwashers and £395 to £950 for passthrough dishwashers.

PLANNED MAINTENANCE AND REACTIVE BREAKDOWN COVER

Maintenance is a crucial aspect of owning a commercial dishwasher that directly impacts its lifespan, efficiency and overall operational cost. Maintenance costs usually fall into two categories: planned maintenance and reactive breakdown cover.

Planned Maintenance

Planned maintenance is a proactive approach involving regular inspections and minor repairs to prevent larger, more expensive issues. It can include checking and replacing seals, verifying and adjusting rinse temperatures, and cleaning and descaling the unit. Regular maintenance ensures efficient operation, prolongs lifespan and reduces the likelihood of breakdown.

The cost of planned maintenance varies depending on the service company, the type of machine, visit frequency (quarterly, biannual or annual), and contract length.

Many suppliers combine maintenance plans with extended warranties covering repairs and replacement parts during the contract period, providing complete peace of mind.

Reactive Breakdown

No matter how diligent you are with maintenance, unforeseen issues can occur. Reactive breakdown cover involves repairing or replacing parts in response to unexpected faults. Costs vary significantly depending on the issue and labour required. Setting aside an annual budget for unexpected repairs is wise. Many manufacturers offer packages that include reactive cover for predictable cost management.

Together, planned maintenance and reactive breakdown cover ensure your commercial dishwasher remains reliable and cost-effective over time.

EXTENDED WARRANTY: A WORTHWHILE INVESTMENT?

Most commercial dishwashers come with a manufacturer’s warranty covering mechanical failure for one to three years. After this period, businesses must cover repair costs themselves unless they opt for extended warranty or maintenance packages.

An extended warranty prolongs coverage, acting as insurance against unexpected repair costs.

But is it worthwhile?

The answer depends on several factors:

Cost of the extended warranty: Consider the manufacturer, coverage length, and terms. Assess this cost against potential repair expenses.
Reliability of the dishwasher: If the model has a strong reliability track record, extended cover may be less critical. New or unproven models may justify additional protection.
Tolerance for unexpected costs: If an unexpected repair bill could impact your cash flow, extended coverage may offer valuable reassurance.
Warranty terms: Some warranties are comprehensive; others contain exclusions. Always review the terms carefully.

While extended warranties involve additional expense, they can help avoid unanticipated costs, particularly for higher-end machines. Conduct a careful cost-benefit analysis before deciding.

OPERATING COSTS: DETERGENT, RINSE AID AND ENERGY CONSUMPTION

Daily operating costs — including detergents, rinse aids and energy consumption — significantly impact your overall budget over time.

Commercial dishwashers require commercial-grade detergents and rinse aids to ensure high cleaning standards and protect the machine. While cheaper products may seem attractive, poor-quality chemicals can reduce performance and increase long-term costs.

Read our article explaining why it is important to use high-quality detergent and rinse aid to maximise performance.

ENERGY CONSUMPTION

Commercial dishwashers are high-energy appliances, using electricity for operation and energy to heat water. Consumption varies based on efficiency, local energy prices and daily usage.

Energy-efficient models, although potentially higher in upfront cost, can deliver significant savings over time through features such as heat recovery systems and reduced water usage.

WATER USAGE

Commercial dishwashers also consume significant amounts of water, typically between one and three gallons per cycle. Depending on local rates, this can become a notable operating expense.

Understanding the true cost of a commercial dishwasher requires evaluating installation, maintenance, warranties and ongoing operating expenses — not just the purchase price.
