Beko [E 42] fault codewhat it means and how to fix it

Beko print E 42 as its own row with a specific cause: an incorrect electrical wiring connection has been made. Their solution is equally specific — check the cable connection against the values in the technical table and correct it — and they add a line that tells you how to know when it is fixed: when the correct connection is made, the error will disappear. That is an installation problem rather than an appliance problem, and it means the person to call is an electrician rather than an appliance engineer.

There is a contradiction in Beko's own table that is worth knowing about rather than discovering the hard way. The same table, on the same page, gives E 31 to E 45 as an electronic board hardware error, and 42 falls inside that range. So the manual gives two readings of one code and does not reconcile them. The specific row is the more useful of the two: it is more precise, it is far more likely on a hob that has just been installed, and following it costs nothing if it turns out to be wrong.

If the connection checks out as correct against the technical table and the code persists, then the range reading applies and it is a board fault. The timing tells you which you are probably dealing with. A hob that has never worked properly since a new kitchen went in is almost certainly the wiring. A hob that has run for years and suddenly shows E 42 is more likely the board, though a terminal that has slowly worked loose can produce the same reading on an old installation.
