I have a Bosch gas tankless water heater, model GWH 425 EF. The igniter does not stop sparking once the flame is lit. What will cause this?

Your electronic ignition unit is not rectifying through the gas flame, it is a sensitive piece of equipment and has failed.

My GWH 715 ES cannot restart after hot into cold water crossover

Check for obstruction in your watervalve. It has a flow meter, that needs to spin freely. Remove the watervalve and blow through it, you should hear it spin.
Also make sure you dont have an error code showing. Hold down your reset button for 5 seconds to reset an error code and get back to your set temp.

I have a Bosch GWH 425 HNO propane Tankless Water Heater which began intermittently exploding when demand for hot water occurs.

Call a qualified service tech immediately.
Gas explosion indicates dirty combustion parts, and gas is not fully igniting when tankless turns on the gas. So gas builds up and then explodes causing serious damage to tankless, and serious risk to homeowner.
