Hey there, fellow brewers! As a supplier of beer boilers, I've seen my fair share of issues with these essential pieces of equipment. One of the most common problems that brewers face is a beer boiler that's not heating properly. It can be super frustrating, especially when you're in the middle of a brew day. But don't worry, I'm here to walk you through some troubleshooting steps to get your beer boiler back up and running.
Check the Power Source
First things first, you gotta make sure your beer boiler is actually getting power. Sounds obvious, right? But you'd be surprised how many times it's just a loose plug or a tripped breaker. Start by checking the power cord. Make sure it's securely plugged into the outlet. If it's a hardwired boiler, check the circuit breaker panel to see if the breaker for the boiler has tripped. If it has, flip it back on and see if the boiler starts heating.
If the power cord seems fine and the breaker isn't tripped, try plugging another device into the same outlet to see if it works. If the other device doesn't work, there might be an issue with the outlet itself. In that case, you'll need to call an electrician to take a look.
Inspect the Heating Element
The heating element is the part of the beer boiler that actually heats the water or wort. Over time, heating elements can wear out or become damaged, which can cause them to stop working properly. To check the heating element, you'll need to turn off the power to the boiler and let it cool down completely.
Once the boiler is cool, remove the access panel to get to the heating element. Look for any signs of damage, like cracks or burns. If you see any damage, the heating element will need to be replaced. You can usually find replacement heating elements online or at a local brewing supply store.
If the heating element looks okay, you can use a multimeter to test its resistance. A multimeter is a tool that measures electrical resistance. To test the heating element, set the multimeter to the resistance setting and touch the probes to the terminals on the heating element. If the multimeter reads infinite resistance, the heating element is broken and needs to be replaced. If the multimeter reads a very low resistance, the heating element might be shorted out and also needs to be replaced.
Check the Thermostat
The thermostat is another important part of the beer boiler. It controls the temperature of the water or wort by turning the heating element on and off. If the thermostat is malfunctioning, it can cause the boiler to heat up too much or not enough.
To check the thermostat, you'll need to turn off the power to the boiler and let it cool down completely. Once the boiler is cool, remove the access panel to get to the thermostat. Look for any signs of damage, like cracks or burns. If you see any damage, the thermostat will need to be replaced.
If the thermostat looks okay, you can use a multimeter to test its continuity. Continuity is a measure of whether or not an electrical circuit is complete. To test the thermostat, set the multimeter to the continuity setting and touch the probes to the terminals on the thermostat. If the multimeter beeps, the thermostat is working properly. If the multimeter doesn't beep, the thermostat is broken and needs to be replaced.
Look for Scale Buildup
Scale buildup is a common problem in beer boilers, especially if you're using hard water. Scale is a deposit of minerals that can form on the heating element and other parts of the boiler over time. Scale buildup can reduce the efficiency of the heating element and cause it to overheat, which can lead to damage.
To remove scale buildup, you'll need to descale the boiler. You can use a commercial descaling solution or make your own by mixing equal parts water and vinegar. To descale the boiler, fill it with the descaling solution and let it sit for a few hours or overnight. Then, drain the solution and rinse the boiler thoroughly with clean water.
Check the Pump
If your beer boiler has a pump, it's important to make sure it's working properly. The pump is responsible for circulating the water or wort through the boiler, which helps to distribute the heat evenly. If the pump isn't working, the water or wort might not heat up properly.


To check the pump, turn on the power to the boiler and listen for the sound of the pump running. If you don't hear the pump running, check the power cord to make sure it's plugged in. If the power cord is plugged in and the pump still isn't running, there might be an issue with the pump itself. In that case, you'll need to call a professional to take a look.
