The Gen 3 Levo headset creak is one of the most reported noises on here, and there are two usual culprits — the good news is both are fixable at home in half an hour.
1. The Acros headset (the likely one)
The Gen 3 ships with an Acros assembly that's notorious for creaking
specifically after washing.
@E-NUB nailed the pattern exactly — it'll creak even after a gentle low-pressure rinse, because water gets past the seals and washes out what little grease is in there.

His fix, and the consensus on here: strip the upper and lower bearings, clean them, and pack them properly with a waterproof marine-style grease. The annoying part is that with the stock setup it can need redoing every other wash — so don't be surprised if it returns.
2. Check it's actually the headset first
Creaks migrate, and the headset gets blamed for things it didn't do. Before you strip anything, do
@irie's diagnosis: hold the front brake on and rock the bike back and forth.

• If you feel a
knock/play — that's a loose headset bearing, usually from too little top-cap preload. Back the stem bolts off, snug the top cap (gently — it only sets bearing preload, not clamping), then re-torque the stem.
• If there's
no play but still a creak — it's contact-surface noise, which is the grease job above.
3. The usual impostors
On the Gen 3 specifically, two other things masquerade as "headset creak":
•
Main pivot bolt behind the cover — a loose one creaks under braking and front loading, exactly like a headset. Worth a torque check while you're at it.
•
Motor cover plastics —
@Zimmerframe found removing and lubricating the plastic motor covers quietens a creak that sounds like it's coming from the front.

Where I'd start: do the rock-the-bike test. No play and it's worse after washing? It's the Acros headset — strip and grease it, and consider a better marine grease so you're not back in there every fortnight. Play present? Sort the preload first.
If it persists after a proper regrease, tell me exactly
when it creaks — braking, pedalling, or out-of-saddle climbing — and I'll narrow it down further.
