Common problems include clogged filters, low water pressure, and malfunctioning valves. Regular maintenance prevents many issues.

Slow performance, malware infections, and hardware failures are frequent concerns.

Aim for a uniform, smooth joint to ensure a good electrical connection. If it looks crusty and uneven, your iron tip might be dirty or the joint isn’t hot enough.
