Code appears before the cycle starts
You press start, hear a click or two, then the washer refuses to run and shows E42.
Start here: Check for laundry, detergent buildup, or a bent washer door strike keeping the door from seating fully.
Direct answer: On an Electrolux washer, an E42 code usually means the control is not seeing the door lock switch change state the way it should. Most of the time that comes down to a door that is not closing cleanly, a misaligned door strike, or a failing washer door latch.
Most likely: Start with the simple stuff: open the door, check for laundry caught in the opening, make sure the door strike is intact, then close the door firmly and try again after a power reset.
If the washer clicks but will not start, or it finishes a cycle and acts like the door is still locked, stay on the door-lock path first. Reality check: a lot of E42 calls end up being a bad latch or a door that is just not seating square. Common wrong move: slamming the door harder until the strike or latch gets damaged.
Don’t start with: Do not start by ordering a control board. This code is much more often a door-closing or washer door latch problem.
You press start, hear a click or two, then the washer refuses to run and shows E42.
Start here: Check for laundry, detergent buildup, or a bent washer door strike keeping the door from seating fully.
The washer has finished or nearly finished, but it acts like the door is still locked or still reading the lock wrong.
Start here: Try a full power reset first, then inspect the washer door latch opening for damage or debris.
The washer may start only if you lean on the door, lift it slightly, or close it just right.
Start here: Look closely at hinge sag, loose hinge screws, and a cracked washer door strike before blaming electronics.
Nothing looks obviously wrong from the outside, but the washer still throws E42 consistently.
Start here: That pattern points more strongly to a failing washer door latch assembly or its wiring connection.
A sock, heavy gasket fold, detergent residue, or a slightly shifted load can keep the latch from seeing a clean closed-door signal.
Quick check: Open the door and inspect the opening, gasket edge, and latch area for anything caught or built up.
If the strike is cracked, loose, or not entering the latch squarely, the washer may click but never confirm the lock.
Quick check: Look for a worn, bent, or broken plastic strike and see whether the door has to be lifted to line up.
This is the most common actual part failure when the door closes normally but E42 keeps returning.
Quick check: Close the door slowly and feel for a weak catch, inconsistent click, or no solid engagement at the latch.
Less common than the latch itself, but possible if the code is intermittent or started after vibration, moving the washer, or previous repair work.
Quick check: Only after unplugging the washer, inspect the latch connection area if it is safely accessible without major disassembly.
A brief control glitch or a door that is just barely not seated can throw the same code as a bad latch.
Next move: If the code clears and the washer starts normally, the problem was likely a bad door close or a temporary lock-state glitch. If E42 comes back right away, move to the door strike and alignment check.
What to conclude: You have ruled out the easiest no-parts fix first.
A damaged strike or sagging door can mimic a failed latch, and it is easy to miss unless you look straight at it.
Next move: If tightening or realigning the door lets the washer start consistently, the latch was likely fine and the door was simply not meeting it correctly. If the strike looks damaged or the door still will not line up, the strike is the next likely fix. If the strike looks good and alignment is solid, the latch becomes the main suspect.
What to conclude: This separates a simple mechanical fit problem from an actual latch failure.
Soap residue, broken plastic, or a jammed latch opening can keep the lock from switching even when the door looks shut.
Next move: If clearing debris restores a normal close and the code stays gone, you likely had a simple obstruction. If the latch area is clean but engagement still feels weak or the code returns every time, plan on the washer door latch assembly as the likely repair.
By this point you can usually narrow E42 to either the washer door strike or the washer door latch assembly without guessing at bigger parts.
Next move: If your inspection clearly points to one of those two parts, you can move ahead without shotgun-ordering multiple components. If you cannot tell whether the problem is the strike, latch, or wiring, it is time for a service diagnosis instead of guessing.
The last step is either replacing the clearly failed door part or handing the job off with enough detail to avoid wasted labor and wrong parts.
A good result: If the washer starts and finishes normally, you have confirmed the fault and can put the machine back in service.
If not: If E42 remains after a confirmed good strike and latch, the problem is likely in the wiring or control-side sensing and needs meter-based diagnosis.
What to conclude: You either finish the repair cleanly or avoid wasting money on deeper electrical guesses.

It usually means the washer is not seeing the door lock switch change state correctly. In plain terms, the machine thinks the door lock system is not doing what it should.
No. Most of the time it is a door-closing issue, a damaged washer door strike, or a failing washer door latch assembly. A control board is not the first thing to suspect here.
Usually no. The washer may refuse to start, may stop mid-process, or may leave the door lock behavior unreliable. It is better to fix the door-lock issue before regular use.
That usually points to alignment trouble or a worn washer door strike. The latch is only seeing the right position when you force the door into place.
If the door strike is good and the new latch is confirmed correct for the model, the next suspects are latch wiring, connector damage, or control-side sensing. That is the point where a meter-based service diagnosis makes sense.
