The Toyotomi OM122DW on-demand water heater typically doesn't have a physical reset button like some traditional tank-style water heaters. If you're experiencing issues with your water heater, there might be a few troubleshooting steps you can take:

1. Power Cycling: Turn off the power to the water heater by switching off the circuit breaker or unplugging it if it's a plug-in unit. Leave it off for a few minutes and then turn it back on. This action can sometimes reset the system and resolve minor issues.
2. Check for Error Codes or Indications: If your Toyotomi water heater has a digital display, it might show error codes or indications for any problems it's encountering. Consult the user manual for the OM122DW to understand what these codes mean and how to address them.
3. Inspect Gas Supply: Ensure that the gas supply to the water heater is uninterrupted and that the gas valve is fully open. If there are any issues with the gas supply, it might affect the water heater's performance.
4. Check Water Supply: Ensure that the water supply to the unit is adequate and that there are no blockages in the pipes leading to the water heater.
5. Contact Support: If you've tried these steps and the issue persists, it might be best to contact Toyotomi's customer support or a certified technician. They can provide specific guidance or schedule a service visit to diagnose and fix any issues with your water heater.

Regarding a physical reset button specifically labeled as such, it's important to consult the user manual as the location and method for resetting the unit can vary between different models and versions of the Toyotomi water heaters. If you don't have the manual, you might be able to find it online on Toyotomi's official website or by contacting their customer support.

Losing pendant displays on cool to cold mornings with your Bosch Highflow 25 EC hot water heater could be caused by temperature-related issues affecting the display module. Cold temperatures can affect electronic components, causing them to malfunction. It's possible that there could be a loose connection, moisture buildup, or a fault in the display module itself. I'd recommend contacting Bosch customer support or a qualified technician to diagnose and fix the issue.

Sounds like the internal seals may be worn. Replace the pump.
