Throughout the mine's history, it had problems with water being situated by a lake. A pile-dam was built during the 17th century, and water- and wind-powered pumps were used. In 1728, at the initiative of Mårten Triewald (1691–1747), a steam-driven pump was installed, a Newcomen atmospheric engine, the first in Sweden, but it was never a success. The failure was probably due to the technology, which worked flawlessly in England, being new to Sweden and was run by inexperienced staff. During blasting to remove two waterfalls in the 1750s, water swept away a blast furnace, a mill and two sawmills. Despite a newly built dam, the mines were flooded in the spring flood of 1795 and it took until 1815 before the situation became normal. In 1805 a new steam engine of 10 horsepower was installed.
