Expect door lock not engaging first. A washer is designed not to run with the door unlocked or the water off, so most of these complaints are the machine doing exactly what it should.
What the washer is actually doing
- A delay-start indicator is showing — The machine is waiting deliberately and will run when the delay expires.
- Nothing at all — no lights, no sound — A dead panel is a supply question before it is an appliance question: breaker, socket, plug.
- The door lock clicks but the cycle does not begin — The lock is made, so look at the water supply and the cycle selection next.
- NEAR MISS — it starts and then stalls partway — A cycle that begins and stops is a cycle fault, and that page ranks the fill, drain, lock and balance gates.
Causes, most likely first on a Lamo washer
- Door lock not engaging — No washer will run with an unlocked door. The lock is a safety interlock, and when it does not make, the machine is dead by design however healthy everything else is. First, because nothing else on the list explains as many of these calls, and ruling it out costs nothing but a few minutes. With a badge like this the practical question behind every check is whether the fix needs a part at all, so the no-part causes are ranked first.
- Inlet hoses kinked behind the machine — Taps closed during plumbing work and never reopened are the classic version, and the fault then appears days later when the machine is next used. Second, and worth checking before anything is taken apart, since it is visible from outside the machine.
- Child lock on, or a delay start set — A cloth wiped across a touch panel is enough to set a lock, so this appears most often the day after the machine was cleaned. It belongs at this point because by now the field has narrowed and the remaining checks cost more time.
- Control board, start switch or lock circuit failed — When power is present, the door locks, the panel is unlocked and water is available, what is left is the electrical path: the start switch, the lock circuit and the board. That is a meter and a part rather than a check. Last, and deliberately so — it should be where a diagnosis ends rather than where it starts.
Check in this order, and why
- Check nothing is trapped in the seal around the door — A corner of fabric holds the door a fraction open and the lock cannot make. First, because it separates the top two causes in under a minute.
- Check both supply taps are fully open — Part-open is enough to stall a machine without stopping it outright. Next, because it takes the same few minutes and covers the other likely half.
- Select a cycle from scratch and hold start where the machine requires it — Some panels arm on a short press and only run on a held one. Only worth doing once the two above are ruled out.
What to do, step by step
- Clean the lock face and the catch, then close the door firmly — Never wedge or force a lock: it is the only thing stopping a drum turning with the door open.
Tools: clothAbout 15 min
- Straighten any kink in the inlet hoses behind the machine — A crushed hose restricts the fill exactly as a closed tap does.
Tools: torchAbout 20 min
- Clear the child lock using the panel combination and select a cycle — It is usually a press and hold of several seconds on a marked button.
About 10 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not a line worth crossing for a fault that is already narrowed to two causes.
Read this before you start
Safety
Power off at the wall before any panel comes off, and close both supply taps before disconnecting a hose. Never wedge or bypass the door lock to make the machine run: it is the only thing stopping a drum turning with the door open.
When to hand it over
Call an electrician rather than an appliance technician if the breaker trips when the machine is switched on, or if the socket is dead with the breaker closed. That is a wiring fault and no washer part will fix it.

What is not on this page
What you are reading is written for the class, not for one Lamo model. A family- or model-specific page, where one exists, carries what this page cannot: the exact part numbers, the board layout and the disassembly order for that line. Go there first if your model is named.
