Before You Call Anyone
Two brand habits matter. Bosch owners should always check the small drain pump cover in the tub floor is clicked down before suspecting the pump, it causes E24 and E25 on its own. And any leak-family code (Bosch E15, Samsung LE) means stop and find water first: switch off, and do not keep resetting a machine that is telling you it is leaking.
