When you turn on your sink or shower, you expect hot water to come out. Finding no hot water and having to take a cold shower streaming out can be unpleasant in more ways than one. The water heater is not working; the problem that is often encountered after a long period of use is a problem that can be caused by various reasons. Including the water heater not heating and the low water flow rate are both annoying problems for people addicted to hot showers. HomeGuru would like to invite everyone to find the causes of the water heater is not working issue and how to fix them.

• Common reasons why water heater is not working

Most water heaters will last a very long time and are rarely troublesome. If there is a problem, it is usually a water heater that has been in use for a long time, so it has deteriorated over time. Or if it is a water heater that has just been installed, it may be because it is an old model that has been in stock for a long time or maybe caused by a non-standard installation. The most widespread problem of the water heater is the water, not heating, which can be caused by various reasons.

1. Overheating and Melted Coil

When using a water heater with a coil system, turning on the water heater to use it, a green light is coming on, but there is no heat like a low water flow rate. The cause may be that the coil is overheated and melted, causing the system inside the machine not to work normally. Or if the water heater is used round rotary switch or a push-button. It may be a problem caused by the fuse inside the part that controls the temperature regulator torn as well, in which case it is recommended to contact a technician to check and fix it.

2. Malfunctioning Thermostat

A thermostat is a device that cuts off heat when a dangerous limit is reached. Usually positioned beside the boiler or coil. If the thermostat has a problem, it will result in the water heater is not working. This may be caused by the water remaining in the boiler for too long, or it may be caused by a wrong installation that does not connect the water inlet. The solution is to buy a new thermostat and replace it, but if you are not confident about fixing it yourself, you can contact a specialized technician to check and fix it.

3. Electric Water Heater Malfunction

Another reason why many people understand that the low water flow rate is that there will be a turn on and there is a green light, but no heat comes out. That could be because the heat regulator has a problem or the Triac device is broken. And there may be a problem with the water pressure sensing bulb as well. This is because these two parts are next to each other and often have their own problems. If there is a problem from this section, it is recommended to contact a technician to fix it because it is a rather dangerous point.

4. Wrong Connected Anode Rod

This problem can be noticed when increasing the temperature of the water heater how much. The water that comes out colder. This may be because the magnetic stopper inside the appliance responsible for turning the electric current for heating has a problem caused by the flow of water over a long time, causing it to damage or deteriorate. This causes the magnetic poles inside the device to alternate. Until causing the warmer water to turn back, the colder it becomes, which can be solved by buying spare parts to replace it.

5. Non-Standard Installation

Anyone who has a problem with the water heater is not working since the beginning of the installation. That may be because it was installed incorrectly or was not installed as standard in the first place. So, if you have read and followed the steps in the installation and use the guide carefully, and still can’t fix it. It is recommended to contact a technician who installed it for a thorough check again. But if it is found that the problem is not caused by installation but is a problem with the device and is still in the warranty period, you can change the product with the shop.

• Common causes of low water flow rate

In addition to the water heater not heating, another equally common problem is that the water flow is not strong enough. This problem can occur since the installation is complete or may occur after using it for a while. And it can happen for a variety of reasons as follows:

1. Scale in Heating Systems

One of the most common causes is scale build-up in the water heater heating system. Since the water taken through the water heater is not filtered well, impurities are mixed with the water, causing the scale to settle in the heating system. Therefore, if the water heater is a low flow rate from this cause, it has to fix the water source’s filtering process by possibly installing an additional water filter.

2. Dirt Clogged in Water Pipe

Another point that often causes problems with low water flow rate is the inside of the water pipes that may be clogged with dirt, making the water difficult to flow. In particular, the longer the plaque is left, the more it accumulates and clumps together, eventually causing the water pipes to become clogged. The initial solution is to install additional water filters as well.

3. Low Water Pressure

Low water flow rate problems caused by insufficient water pressure are common in townhomes with two floors or more. Especially in the upstairs bathroom, this is because the water supply pressure is too weak. This causes the pressure sent up to the water heater to be uneven. This problem can solve by installing a water pump with a wattage suitable for the size of the house. So that the water heater can be turned on at the same time without problems.

4. Improper Household Voltage

In addition to the water pressure factor, many people may not know that the voltage in the home can also be related to the low water flow rate problem. Before deciding to buy a water heater, you must first check whether the electricity meter at home can support the voltage of that water heater or not, because if the voltage at home and the water heater is not related. It may cause low water pressure, including problems with power outages, and causing the water heater to deteriorate faster than it should be

However, if the electricity meter at home is a meter size 5 (15) A, it is recommended to choose a water heater that does not exceed 3,500 watts. Still, if it is a meter size 15 (45) A, selecting a water heater that does not exceed 4,500 – 6000 watts is recommended.

5. Heating System is Damaged or Deteriorated

For homes that use water heaters continuously for a long time, there may be problems with the low water flow rate. One of the reasons is the internal heating system is damaged or deteriorates over time. The correction, in this case, is recommended to be the duty of a specialized technician.

6. Boiler is Leaking Water

It is a common problem with cheap water heaters that reduce production costs by using low-grade plastic to make the boiler inside the appliance. When used for a while, a leak will affect the water pressure through the machine. Therefore, choosing a water heater that uses high-quality materials, such as a water heater with a copper boiler. Or a high-quality plastic boiler like Grilon is highly heat resistant, durable, does not leak easily. It will help prolong the life of the water heater and not cause problems with low water flow.

7. Silicon Rubber Ring is Too Small

O-ring or rubber seal is an important device used to support various hose connections, including the hose that connects to the water heater and the shower hose. It prevents leakage at the joint. But if this rubber ring is too small, it is difficult for water to flow through. The solution is just to remove the cable joints at various points to check if there is any point where the rubber ring is too small and replace it with a new larger one.

8. Using Shower Water Filters

Some people may not realize that another factor that can cause low water flow rate problems is using shower heads with multiple water filtration systems. A good quality showerhead usually has several layers of internal water filtration to help trap any impurities that may mix in the tap water or to help regulate the current according to the showerhead’s adaptive function. But if the shower has too many layers of water filtration, it may also be an obstacle to the water pressure.

The water heater is not working, and low water flow rate problems can arise for various reasons. From non-standard installation, poor quality water heaters, and various environmental factors can cause this annoying problem. To correct the point, it is necessary to find the exact cause first. Including when fixed, it is required to regularly inspect and maintain the water heater to avoid repeating the same problem.
