Bosch DISHWASHER – stops close to end of cycle with E19

Bosch DISHWASHER – Built in.
E no. SMV46GX01G /03
FD no. 9709
Z no. 00292

The machine is 3 months over 2 years old but Bosch will not provide good will warranty.

Machine operates – drains, washes, rinses and gets close to end of cycle (drying cycle) but then stops with beeps and E19 Error Code.
This is a latched error and machine cannot be restarted without power cycling.

I have changed the Heat Exchanger solenoid valve but no difference.

I can confirm that there is no water in the machine base – machine reports a separate water warning / error on that condition.

Does anyone have the route cause guidance on E19 on these later appliances?

What I’ve read….

• Most hits suggest Heat Exchanger Valve. That’s been changed.
• Then water in machine base which doesn’t apply to this machine as it has a separate water interlock icon which I have tested.
• Then tablet dispenser but that is working so I’m loathed to change without specific evidence.

E19 seems to be a later Error code so not so much info around.

Any help would be appreciated.

Many thanks
