There is a small puddle of water underneath. Goes away if tap turned off between washes. Is at front only so not a leaking supply or drain pipe. Not sure if there is excess water inside which could be a sign of a leaking inlet valve.
Door seal looks clean and in good condition.
Is there a common cause of this on these machines?
I had a leaking inlet valve on another non-Bosch machine but it set off the drain pump as there was a float switch in a sump under the main wash cavity to detect overflows.
