Keeping Your Commercial Dishwasher’s Boiler Efficient


The boiler in your commercial dishwasher is a crucial component. If the boiler fails, your dishwasher isn’t going to be sanitising dishes correctly. 

Your commercial dishwasher’s boiler can be susceptible to problems with calcification, corrosion, or electrical faults. To avoid these issues, it’s essential to follow some simple maintenance and prevention guidelines. 

 

Why Boiler Efficiency Matters

A well-functioning boiler is key to:

•    Consistent Wash Quality: Ensuring dishes are properly sanitised
•    Energy Savings: A clean, efficient boiler uses less power
•    Reliability: Reducing unexpected downtime or costly repairs
•    Longevity: Extending the life of your dishwasher and its components. 

 

How To Maintain Your Commercial Dishwasher’s Boiler

 

1.    Descale Regularly

Limescale buildup is a boiler’s worst enemy. It reduces heat transfer, increases energy use, and can lead to overheating or component failure. Check daily for chalky white deposits, and arrange a proper descaling, ideally by a technician, if you spot buildup. 

2.    Regularly Check Heating Elements

Regularly check the condition of the boiler’s heating elements, which overloads or short circuits can damage. In case of anomalies, replace the heating elements with original or compatible spare parts. 

3.    Check the Boiler Thermostat

Check the correct functioning of the boiler thermostat, which regulates the water temperature. If the thermostat is defective, the water may be too hot or too cold, compromising the quality of washing. A qualified technician should replace the thermostat.

4.    Protect the Boiler from Power Surges

Protect the boiler from power surges or power cuts, which can cause irreparable damage. It’s advisable to install a surge protection device or an uninterruptible power supply. 

5.    Use the Right Chemicals

Only use detergent and rinse aids approved for use with commercial dishwashers. Dishwashers direct offer specialist chemicals designed for high-demand environments. Overly aggressive cleaners or bleach can damage seals and heating elements; therefore, always follow the recommended guidelines. 

6.    Flush and Clean the Boiler Tank

Follow the manufacturer’s instructions to flush the boiler at scheduled intervals. This prevents sediment and debris from circulating, which can impair heating efficiency and clog internal components. 

7.    Maintain Optimal Water Softness

Hard water accelerates limescale formation. Where possible, install water softeners or reverse-osmosis systems from the Essential Accessories range at Dishwashers Direct to protect your boiler and reduce the need for frequent cleaning. 

8.    Pre-Rinse Dishes Thoroughly

Minimise solids entering the system by scraping or rinsing dishes before loading. This protects filters and reduces strain on the boiler and circulation systems.

9.    Schedule Planned Maintenance

Even if everything looks fine, periodic checks from a trained engineer (like one from Dishwashers Direct’s specialist team) can identify early warning signs such as minor leaks or limescale on hidden components, before they become a serious problem.

 

 

What Not to Do

•    Don’t Ignore Limescale: Small deposits left unchecked can become large, expensive issues.
•    Don’t Use Abrasive or Corrosive Chemicals: These can harm pipes, valves, and seals.
•    Don’t Overload the Machine: This strains the boiler and prevents proper circulation, shortening lifespan.
•    Don’t Skip Filter and Drain Checks: Clogged systems place extra pressure on the boiler and pumps.
•    Don’t Wait for Failure Signs: Sluggish performance, odd noises, or poor wash results are early signs. Acting earl avoids more costly, reactive repairs.
