Customer had stated that the water wasn’t getting hot in the home. Opened the utility closet and inspected the unit. There were no active codes happening with the unit upon inspection. Ran water in the home and noted hot water being produced by the tankless unit. Did notice a slight fluctuation in the temperature but both bathrooms in the home are multi handle valves and can’t be the source of any cross connections. Advised customer to wait at least a day before jumping to unit replacement to see if any more tangible symptoms show themselves. Will proceed with any replacement options from there.
