A water purification apparatus, comprising a water pump, wherein the water pump inlet port receives water from an external source, a nonreturn valve in fluid communication with the water pump outlet port, and an ionizer chamber in fluid communication with the nonreturn valve output end, wherein the ionizer chamber doses a bacteriacide into water contained in the ionizer chamber. The heating element may have a center axis and be positioned near the fixing member inner surface such that the heating element center axis is spaced from the fixing member central axis. A processing module performs a simulation of a service selection procedure based on the service selection protocol and performed in accordance with the signal monitoring program and the signal emulation output. At least one temperature-sensing circuit is coupled to a fourth IO pad. Optionally, the base may be attached to both the seat portion and the actuator.
