Troubleshooting, Maintenance | Whirlpool T-K1S guide

Maintenance

WARNING: Turn off the electrical power supply, the manual gas control valve, and the manual water control valve before servicing.

The unit should be checked once a year or as necessary by a certified and trained technician. If repairs are needed, the repairs should be done by a certified and trained technician.

The following systems and parts should be checked at least once a year:

1.Venting systems

2.Burners

3.Manual operation of the pressure relief valve to ensure correct operation.

4.Periodic cleaning of the water filter, refer to figure below.

5.Heat exchanger. Remove the thermistor and check for a mineral coating . A mineral coating on the thermistor requires flushing the heat exchanger with a descaling solution. Scale build up will void your warranty and shorten the life of your water heater.

Troubleshooting

Water Isn’t Hot Enough

The T-K1S can burn gas at a maximum input rate of 190,000 BTUH. This puts a limit on the possible output temperature and flow capabilities (See flow chart on the last page of this manual). If the water doesn’t seem hot enough, compare the flow and temperature that is being attained to the T-K1S flow vs. temperature chart. If the unit is not performing according to the chart, first check that the gas supply line is sized properly, and that the gas pressure is within the required range. If the gas line is okay, check the plumbing for mixing valves, thermostatic valves, scald protection, single handled valves or crossed connections. If the unit is performing in accordance with the flow chart, then it may be undersized for the application. If the unit is performing according to the chart, the output temperature can be adjusted using the T-K1S.

It Takes Too Long to Get Hot Water

The T-K1S takes three seconds to ignite, and three more to get up to temperature. The rest of the time needed for hot water to get to a fixture is due to the length of piping between the water heater and the fixture. If the unit seems to be taking longer than six seconds to initiate, check the filter and flow sensor for any debris or damage.

The T-K1S Will Not Initiate

First check the flow rate through the unit. If the flow is not 0.75 GPM or greater, the unit will not initiate. Check the filter and the flow sensor for any debris or damage.

Press the lower green button on the GFCI inside the unit. If the red light above it does not come on, then there is a problem with the electrical supply to the unit. If that light does come on, hit the green reset button above the light, and look for the green light on the circuit plate at the top left of the unit. If this light is not lit, there is a problem with the electrical connection between the GFCI and the circuit plate. Contact Takagi Industrial Company for instructions.

T-K1S specifications

The Whirlpool T-K1S is a cutting-edge tankless water heater designed to provide endless hot water while maximizing energy efficiency. This model is part of Whirlpool's commitment to innovative technology and superior performance, making it a popular choice for both residential and commercial applications.

One of the standout features of the T-K1S is its on-demand heating capability. Unlike traditional water heaters that store hot water in a tank, the T-K1S heats water only when needed. This eliminates the need for a storage tank and reduces the risk of running out of hot water during peak usage times. Homeowners can enjoy continuous hot water, making it ideal for multiple simultaneous uses such as showers, dishwashing, and laundry.

The T-K1S is equipped with advanced technology that optimizes energy use. With its high-efficiency rating, it significantly reduces energy consumption compared to conventional water heaters. The built-in digital scale allows users to set precise temperatures, ensuring comfort while also promoting energy conservation. This feature also helps to minimize the carbon footprint, making the appliance an eco-friendly option.

Safety is a paramount consideration in the design of the T-K1S. It features multiple safety mechanisms, including a robust thermal control system that prevents overheating. The unit also has a built-in safety shut-off mechanism which activates in the event of water flow disruptions, ensuring peace of mind for users.

Another noteworthy characteristic of the T-K1S is its compact design. The space-saving design offers flexibility in installation, allowing it to fit in small or tight spaces, such as utility rooms, basements, or even closets. This feature is especially beneficial for those with limited room for traditional, bulky water heating systems.

Durability is another key aspect of the Whirlpool T-K1S. Constructed with high-quality materials, it is designed to withstand the test of time, minimizing the need for repairs or replacements. Whirlpool also offers excellent warranty options for added security on your investment.

In summary, the Whirlpool T-K1S is an exceptional tankless water heater that combines efficiency, safety, and durability. With its on-demand heating technology, energy-saving features, and compact design, it represents a smart choice for anyone looking to enhance their hot water supply while being environmentally conscious. It embodies Whirlpool's commitment to quality and performance, making it a leading option in the market.
