I have a two year old Generation 1 HPWC (now called Wall Connectors) that just died. It has not had very heavy usage. Have others had HPWC's die on them? Further info: • It was installed by a qualified electrician. • The HPWC now gives 7 red blips as an error code. Tesla service tells me that this means that the unit is dead and needs to be replaced.
