Commercial dishwashers are an important part of the commercial kitchens. These machines are designed to wash and clean multiple dishes throughout business days. As such, it is normal for them to run into problems. However, you should have an idea of how to troubleshoot and diagnose the issue so you can try to run the appliance while the commercial appliances repair expert is on the way. Here are some common problems along with their fixes to help you kickstart the process.
Dishwasher Not Starting
One of the most common problems with commercial dishwashers either being new or old is not starting. It might seem a complicated issue to fix as you will need to check and inspect multiple things but if you know where to look, you will most likely be able to diagnose the issue within a few minutes.
For instance, the first thing you need to check is the power outlet and cord. Sometimes, power outlets burn due to a power surge. Try unplugging the dishwasher and plug it into another outlet. If the dishwasher works, it means the outlet will need to be replaced.
At the same time, check the power cord as well. This is a common issue amongst older units where power chords tend to develop cracks and simply wear out with time. As a result, the cord is not able to transfer sufficient power to the unit. In both cases, you will need a replacement of the power cord, which is something you can do on your own if you have the required skills and tools.
Dishwasher Not Cleaning Dishes Properly
Commercial dishwashers are heavy-duty machines specifically designed to handle huge amounts of workload daily. These units are equipped with smart technology and the dishes go through multiple stages of the washing process. This means the dishes should come out squeaky clean every single time.
However, if you observe that the dishes are not as clean as they are supposed to be, you will need to consider several reasons. To begin with, check the filters. Filters are designed to trap food, dirt, and other external particles. If the filters are clogged, the unit will not be able to perform as it should.
Next, check the wash, and rinse arms and jets. The jets help clean the dishes by directing high-pressure water. Not cleaning or maintaining the dishwasher can cause jets to clog as well. Limescale is another major reason such components may fail to deliver. Therefore, check the manufacturer’s recommendations for cleaning the dishwasher.
Dishwasher Stops Filling
A commercial dishwasher not filling is a slightly complicated problem. The first thing you need to check is the water inlet valve. Check the filter and make sure it is not dirty. Then, check to ensure the valve is not sticking. Debris can hinder the performance of the inlet valve.
If that does not solve the problem, move on to inspecting the float. It might be that the float is damaged. Ensure that it floats freely and does not have any signs of wear and tear. If there is something wrong, it will cause the float switch to shut off too early.
Dishwasher Not Draining
Dishwasher not draining is perhaps the most common problem amongst both household and commercial units. There could be several reasons contributing to the issue, which means you will need to look in the right areas.
For instance, ensure there are no drainage obstructions or no power or cycle issues. Furthermore, check the drain pump as it is responsible for draining water at the end of the wash cycle. Components like selector switches, the inlet valve timer, and the electronic control board can also prevent the dishwasher from filling up.
Not only that but also the impeller and rinse pumps wear with age, which causes them to lose power. Depending on the make, model, and variant of the unit, there may be one or more impellers. On the other hand, if you hear strange noises while the machine is running particularly from the rinse pumps, it means a replacement is due.
In such cases, you will need to consult a commercial kitchen appliance repair Alexandria technician who will perform the replacement tasks. Keep in mind that you will need an exact replacement for which contacting the manufacturer will be a wise decision rather than buying from other sources.
Dishwasher Is leaking
A leaking dishwasher is another extensive problem requiring extensive inspection and diagnosis. Dishwashers can leak due to a variety of reasons. The first thing you need to do in such cases is identify the source of the leak. If you are lucky, you might be able to spot the leakage in deteriorating seals, pipe fittings, and other parts.
Rust and corrosion tend to be a major factor causing leakages. Boiler and rinse tanks are the most affected parts in this case. Rust and limescale buildup can easily create problems. As a result, you can either choose to get your dishwasher periodically maintained by an expert or simply opt for replacement parts.
In addition to that, O’rings, door seals, gaskets, etc. can also contribute to leakages. Since these parts are mostly made using plastic, they will need to be replaced after a few years. Unfortunately, there is hardly any way to prevent replacements as these parts come with a lifespan.
Considering a commercial dishwasher being used throughout the day, it is normal for such components to wear out with or before time.
How Can Commercial Dishwasher Issues Be Prevented?
The best way to prevent commercial dishwasher issues is by scheduling professional maintenance. At the same time, follow the manufacturer’s recommendations as well. Most people think that professional maintenance is just a way for companies to earn money but it saves you from a lot of expensive repairs and replacements down the road.
Although basic inspections and cleaning can be done by the staff, some inaccessible and complicated areas need to be looked after. Professionals in that respect, possess the knowledge, skills, and experience and have the right tools to inspect, diagnose, clean, and replace parts.
That said, professional maintenance is more of an investment rather than an expense. If you are running a restaurant, the last thing you would want is the dishwasher giving up. With no dishware to serve meals, you are supposed to panic.
However, professional maintenance helps avoid all such issues and keeps the machine running effortlessly.
Is Professional Maintenance Expensive?
Professional maintenance will only be expensive if the machine is neglected and the expert has to put in a lot of effort and time to clean up the machine or diagnose the problem. Regularly, it should not cost you more than a few hundred dollars.
Instead of ignoring the maintenance and saving money, think of spending a bit and ensuring the machine works without causing any damage to your business.
Diagnosing commercial dishwasher problems can both be simple and difficult. Regardless, you should consider the tips above to have a head start in the diagnosing process. If things seem far more complicated, call a commercial dishwasher repairs Fairfax service and make sure to schedule periodic expert maintenance based on the usage frequency. Ignoring maintenance will increase the appliance breakdowns.
